You literally just answered my question with this entire video and the question was why is my engine feeling so laggy but I have no engine light popping up.? And you just answered that thank you so much I've been looking all day for this
I don’t think there is anyone on CZcams with this much knowledge on BM’s
This guy is the BM god
Dude, thank you! Clogged cats are not a myth. I've been chasing down a major loss of power on my e36 325i. I ripped off the exhaust and there she was. That midrange BMW torque. I was about to replace the clutch because I thought it could be slipping...
Did you finally get the desired power on your bmw? I'm sitting with a same problem
insta like all your videos! ive watched them while working on my 03 330ci and they always help me out! hope your channel blows up you deserve it!
PERFECT timing for this video! My catalytic converters are making rattling noise on start up according to my mechanic and I did notice power loss. Thanks for the video
Michael Moshi did you end up replacing your cat? How did you fix why your cat died in the first place?
Thank you. I have had this problem for 3 weeks now and there is a sound coming out of the catalytic converter but one mechanic had said I had an engine knock. Glad to have watched this video
When you remove the oxygen sensors, do you leave them electrically plugged in on the test ride?
Make this guy King. He knows what he' doing!!! the video is tops!!!
One of The People one year later no reply 😂. Don’t you just hate some youtubers 😂
Yes you can leave them plugged in.
@@Grumps5 thanks, a tad late though.
friendly coconut the mechanic here
depends on what kind if o2
if its a heated core unplug it and remove it, and full honesty this is a terrible way to test for a clogged cat, you shouldn't let hot toxic fumes out in the engine bay they are a significant carcinogen all thats going right into the cabin where your sitting that is why states have laws that prevent people from having exhaust that can enter the cabin that and it could cause issues with wiring if you have it right next to the o2 considering that it will be the upstream youd remove, if you do go this route remove it some of the cores can get hot enough to melt through wires so best safe than sorry not all heated cores are equal some require ground to the exhaust what you should do is take your car to a mechanic and do an exhaust gas pressure test for the upstream sensor this test will tell a good mechanic that there's too much pressure buildup before the cat which will cause the aforementioned issues
Thanks for the tip, exact same car but it drives fine until I attempt to accelerate quickly then the motor boggs down and appears to enter like a safe mode .. which resets with a restart of the motor and it drives normal again. Drives fine as long as you baby it, any heavy acceleration and it does the boggs down again.... Thoughts? Thanks
Ken Parks hey did you figure it out? Plz respond
Hi my E46 does the same thing. Any ideas on how to fix it or what it can be?
Vanos is toast
Good ,useful advice , great tip, thanks Jason. Cheers Ricardo from Australia ( merc c180 w203 .2000 model)
this happen to me, oddly enough I replace vanos seals on 330ci and fuel injectors and it started working again. smooth power and engine doesn't rough idle anymore. just in case someone needs this info.
Was your engine working rough (shaking badly) when idling in gear just after startup?
Lucky Luke if you experience shaking that means your 02s are plugged into the wrong harness so switch them up on the engine bay
Lucky Luke I know this is late but did you ever fix this? because mine is doing the same thing.
Jason can you make a video on how to replace the vacuum hoses on the M54 engine? My hoses are cracked and want to DIY but they are behind the engine the one that is cracked.
Thank you, I think that is the Problem with this 1992 Civic , I changed everything , it still crank but after a minute go off, Finally that is got to be the problem.
and what kind of seals are you saying? my car cuts out at about 2500 like its not getting fuel.
Hi,
My 2006 X5 E53 3.0i runs sluggish and the "After" O2 sensor needs replacing. I went to a mechanic but he dismissed the idea of the sluggishness being related to the O2 sensor. I'd appreciate if you could advise and identify any other areas that might need attention. The truck has 200k kms on it. Thanks.
Thanks for this video! I bought my first e36 325i with similar problems that you are talking about. Now it’s just time to inspect
Single vanos ?
you mentioned vanos seals. I have an Opel Zafira - and experience sluggishness between 2 and 3 RPMs. My cat was busted replaced it, but I don't feel like I've addressed the 'real problem'. this video is super interesting to me....but I've never heard of the vanos seals issue.
Bit late but vanos seal is bmw specific
Hey Jason I'm a 22 year old mechanic my self. & I'm a former owner of an e46. Currently own a e39 (rebuilt it twice) & 6gen maxima (got for a steal).. I'm looking to get another daily driver but I honestly don't know if I want to find another 03-05 325xi or 07-08 g35x.. Any suggestions or comments will help.
Menace II Society hey im trying buy a bmw e46 318i 1999 model but every car i check i dont see a check engine light before starting the car. is this normal?
Could you do a oil catch can conversion, or video about the e46 oil consumption issue?
Bro I have a F10 N54 engine. Having the power loss issue and no engine light. Would the symptoms be the same?
Did you figure it out?
??!!??
Can a throttle vacuum leak be a reason also? This power loss literally just happened to me but ive had a code for a vacuum leak for like a month bcs im saving up money to just re do my entire lines and hoses but i just experienced severe power loss. Please tell me this cant be transmission related also? Thanks man youre very helpful in your videos.
I ran without the pre cat 02 sensors like I took them out the headers and my performance was actually worse
Is there any DIY for cleaning catalytic converters - E46 325?
Good advice for sure. My problem 2012 Chevy Cruze occasionally loses power and will not accelerate, then works fine again for a few weeks. This happens over and over again. I hear nothing loose or rattling in the catalytic converter. Could there be something temporarily clogging blocking the exhaust flow. Sometimes I will get a catalytic converter inefficiency code. How can I further troubleshoot this problem?
What might cause my car to act this way when starting the engine cold and it being 10-15 degrees outside? Pedal to the floor, car seems to be struggling to get up to speed of 30-50. The weird thing is that once the engine warms up the problem goes away
Jonathan Plugaru same problem here
I wouldn't worry about that. Depends on the car and oil being used. If it is an E46 M3, these should especially *never* be attempted to drive hard from cold as the 10w/60 oil takes a while to reach a decent viscosity level that will properly protect the rod bearings. Best thing to do on a cold start is let it idle for around a minute (or more if possible). This will allow the oil to heat up a bit and circulate the critical engine components (pistons/rings/rods/bearings/crank, etc). You will only flood the chambers by flooring it at cold and prematurely wear the engine internals. A lot of cars, and all E46 M3's that live in a coldish climate will show some kind of low power symptoms from a cold start. If you have a bad idle though, that is different and will need further investigating. Bad idle can range from a dirty MAF sensor, ICV, O2 sensors, clogged injectors, to a vaccum leak. Apart from the MAF on an M3, those would normally be accompanied by a dashboard EML though.
It's a saftey feature so you won't destroy the engine. Just like in the s54 on the tach they have the yellow shift lights then when it warms up it's able to redline. Same concept
I have that issue, i change the transmission oil and filter, and everything back to normal so you can try that it won’t hurt.
Hi Shop Life...I own a 2004 350z automatic. Couple days ago, getting on the freeway, I pushed the accelerator all the way to the floor to gain speed. Usually, the car will go into a lower gear to gain more speed, like a overdrive feeling! Nope! I then removed the throttle body off, cleaned the MAF sensor too. Still still slow slow instant response. The car will go....kind of cruising mode to gain speed. After that went to AutoZone to buy a new MAF sensor....that didn't work either! And btw...no check Engine light at all! What to do? Can you help??
Symptoms....at first small studder while driving , and randomly rough or uneven idle at stop lights.. possible solution..... If possible pull the clip off the injectors one by one. Plugging them back in as you go. If it gets worse when you unplug one plug it back in. I found on my Ford focus that when I unplugged one nothing changed engine ran the same.. The injector was not working anymore . I am going to replace today.
Update. Ended up being coil pack
Hope this helps.
Hey there,
I have a 1997 M3 which looses all electrical power while driving. I pull over and disconnect the battery for a couple minutes then reconnect it and everything is fine again. Usually happens when I am going fast. Any advice will be sincerely appreciated.
Hey Jason, I replaced my downstream 02 sensor and cleared the pending code P013E but the check engine light comes back after driving 15 miles. The OBD II say delayed response- rich to lean bank sensor 2 after replacing Bosch 02 sensor. The car drive great but the check engine will not cleared system. What do you recommend?
Come to Edmonton Alberta Canada and fix my car!! Lol it's driving me crazy
Ahaha im in calgary, alberta and have the same issue with my 330ci
I drive an 04 tiburon gt v6. Out of nowhere it started driving like ass. Like the acceleration isn't really there. And the rpms stop going up at around 3700-4000 rpm. I'm not getting any lights. I can get it up to speed as long as I shift early but it's taking forever to get up to 50-60 mph and I really dont wanna keep driving it like this. :/ any tips before I run it to the shop?
What if Im taking off from 1st gear an press the gass and as you take your foot off the gass the car bucks and isnt a smooth transition to dump the clutch to engage 2nd any recomendations ?
Ive just brought a new inlet manifold
reseal kit for my injectors
Air intake solinoid sensor
Unplugged maf sensor to see if any diffrent
Took off cleaned throttle and cleaned
Full service with new fule filter and fule cleaner and cam postion sensor 😅 im running out of ideas and its starting to cost quite a bit 😂 any help would be great
Its a 1.8t audi a3 8p
I like the o2 sensor test, thanks.
I have no stutter, but I measured my e46 330i and I got 175wHP, and I measured my 0-62 on high 8s... do you have any idea what it might be? I might try the O2 sensors thing tho...
Gustavo hey bro having the same problem on a E46 330Ci, have you figured out what's going on ?
I have to thank you men for this video
Wow nice video. I never thought about the vanos seal will cause a lost of power. I do have a tank vent vavle code. I can't figure out what it could be. I change the vavle no change..beside the vanos seal and the thank vent vavle. What other issue I should look at
Thx for your information ❤❤❤❤❤❤
Great tip but not really useful if you dont make it back from the test drive after exhaust fume asphyxiation.
Do you have a vid on replacing vanos seals?
Thanks for the help informative video. Noticed you’re in Alhambra I’ll definetly call you up for some work.
hey jason i,ve hit you up on IG regarding my 06 X5 transmission fluid change and all that. but now all of a sudden turned it on, on Sunday and it started sputtering and it wouldn't go past 5 mph from dead stop then it gets going but while sputtering down the road also it sputters while sitting idle. service engine soon light also came on.
Thank you for the video. Are you still in SoCal?
I check catalytic converters with a laser temp gun. Run the vehicle til the engine is good and normal temp, then measure exhaust tubing temp before, at, and after the cats. A huge variance will tell you what's going on, and where. My Crown Vic has 4 of these damn things.. I didn't know the very back 2 'silencers', which look like glasspacks, were actually catalytic converters.
i have the same issue, i experienced this after changing fuel filter, can this be the reason for this ?
I have a 2010 bmw x5 e70 diesel. I have a power loss. If im using the heater on full blast and if i speed up the fan motor speed drops
I have a 2007 Lexus IS 250 manual , I have it straight piped but it does the same thing when sometimes I go full throttle, it seems like the car worked better when I re fill it with fuel. Do you think it’s the fuel pump?
Sometimes you can hear and feel the exhaust blowing back through the intake .. when it gets really bad the car would go in to fail safe mode .. very common in the e46 models
Hey man I have a question
Is that sound kind of a echo
Engine light popped up, while l crossed a huge puddle of water, not very deep though. Could that be a sensor issue??
Is there such a thing as retrofitting heated seats? My seats are fully electric with memory position but doesn’t have the heating function
Can this be retrofitted in and if possible can you make a video showing us how to do it?
ShopLifeTv i have a question my 2006 325i haz 90 thousand milles u recommend to replace the trasmission fluid?
I have a e90 330xi and when in neutral it has a rough idle tht bounces up and down between 1 and 2 also when I’m going up hill or down slow the car stalls not to make it any worse I have my dash lit up like a Christmas tree please help 🙏😭?
I have same problem
You should show how to remove the sensors
2004 E46 goes into like a limp mode when I try to go up speed and then I shut it off turn the car back on and it goes back to normal but if I go up to 55 or 60 it goes back to a limp mode what can be the cause of it.
Hey man did you ever get this fixed? This is the same issue with my e46. And i also figured out the ignition off and on again to get the power back. Please let me know if you found the fault.
when I floor the car there is a burbling sound when changing gear. its followed by more burble and if I push the car a bit more it gives me misfire on cylinder 1. My car is 325i E90, straight piped.
Are you supposed to drive it without the o2 sensors for a while?
bagi nanagee no the noise is deafening
wath could it be if im in 2nd gear at 4k rpm all good but then when i change to 3rd i get power loss like the car wont go past 1-2k rpms with my foot down wath could the problem be?
Excellent sounds like my problem, well my friends car. I will try n see.
i just bought a Pre-owned 2005 Audi A6 Quattro. the Car comes to a gradual halt when in motion. i usually have to turn it off and back on again before normal drive is restored. I have changed the Fuel Pump, Four bad Coils, Fuel Filters, Two bad Plugs. Please what should i do to have this resolved or what can you narrow it down to? Any assistance would be welcomed- I have spent a lot on guess works mechanics
You are so right thank you 😬👍
Hey Jason,I have a question/video idea. I own a 2004 330i zhp. I picked it up about a year ago. I used your video to help me change the oil filter housing gasket. I saw oil on the engine, but I thought it would just evaporate as I used the car. Occasionally I get a bad smell from the ac/heat vents. Could it be the oil on the engine? If so what is the best way to clean it. Thanks for your help, Paul
Hey ...how ya doing...a question ...my 02 525 wagon drives good and then hesitates. I shut engine off and then runs good for a while and then does it again ...any ideas...I put alotnof stuff new...throttle body, tune up ...new boots vacuum lines....I 5hink it could be either DME or Cat converters...had diesel in gas before all of this....any help, thx
@shoplifetv car idles bad and no check engine light, done camshafts sensor intake side . Spark plug and the wiring forgot what you call it the thing that goes in the spark plug.
Cleaned idle control valve and changed the boot around the air filter box .
I would really appreciate it if you could just say your opinion to where to look more ?
M54 engine E39 530i 2001 .
Help! I have spoken with nissan many times about losses power with no check lights. Only while going up a steep hill
I have same problem with my Nissan.
if they are cloged. won the engine over heat too ?
Do put the car in idle after you take out both o2 sensor?
Could you use a laser thermometer and check inlet and outlet pipes on converter ?
Good info, thank you very much for making the video!
I like your style only BMW good info
Help me. I have e46 328 got the issue. I already change to new MAF sensor and clean up the ICV until the valve can freely to move, and the Hose to the intake doesnt have any hole. But still got the same issue, my idle sometime bouncing for a while when i turn on the AC. But when the AC shut off, it will again be bounce for a while and then the idle will be okay. Then sometime my car will lost the power if i want to accelerate (feels like the engine choking/get sucked). Please somebody help me. I already blow my mind right now. Or is it my car need 1jz for the heart of this car.
SORRY FOR MY BAD ENGLISH :)
Hi i have a 2015 bmw m6 i step on it on sport plus + with everything to make it go fast and my car moves but the the RPM dont reach the rev limter or even hit them
I'll try this, ford had my escape for 2 days and says there's nothing wrong with it. Daily driver for 2 years, 70k miles, I know how she drives.
I lost control coming off a roundabout I went sideways on a dual carriageway then my car was very sluggish & made a weird light noise. It's currently being looked at
Hey guys! Would this clogged catalytic converter be paired with lots of gray smoke when i try to force the engine?
It runs normally if i accelerate nice and slow, but the engine starts vibrating if i try to go hard - i get gray smoke and it stalls if i keep insisting...
I am having same issue at the shop after wot half light turns on and smokes a lot other than that runs perfect but gotta fix for dealer
Did you find anyting radu?
Did you ever figure out your problem I'm having the same? And I need help
Amazing. Thanks for this video... it helped me....
My 80 Datsun 720 pick up dogs hard when I put the pedal down hard trying to shift through the gears, then stalls over and over again, then it fixes itself, then it starts all over again when I pedal down hard. I change the fuel filter and been tinkering with the accelerator on the carb. I'm gonna ck the coil now :(
Mate thanks alot, you made it easy and simple 👍👍
Have you encountered a battery drain happening every couple of days on any e46? Had this problem last winter and replace the FSR and got a new battery seemed to fix the issue, but it has came back. If i don't drive the car for a a day or two, the battery is dead the following day. Also I notice that my heating is not working (not sure if its related or not), the reason I mention this is because during Spring/Summer/Fall the problem is gone. Any suggestions? I love my car but this is so freakin' frustrating.
I have an e46 m3. Issues I had p0012 and p0014 along with multiple misfire codes. car runs like a cammed muscle car, surging bogging really crappy . no power until 4500 rpm and then the car feels like it has 400 horsepower. I bought a beisan solenoid and sealing plate gasket kit and replace both of these. The car still drives exactly the same, terribly. One thing to note is that the p0014 for exhaust advanced timing has gone away and only the p0012 intake retarded and misfires stay. Can you please offer some advice ? I've spent so much money on this car trying to fix it I am getting really depressed. Thanks @ShopLifeTV
I am driving a hyundai tucson stick transmission ...it lost power after 4th gear on the road ...can you give me an advice please
I have an issue with a 2012 kia soul. Loses power (40 mph)..has happened 2 times in the last 2 weeks. If turn it off and let it sit appears to run fine with good power. No codes. Thought maybe a cat issue at first but if you have a cat issue shouldn't you have it all the time once you experienceit the first time?
hi there i have got 1 series 116d today while going 60 suddenly drop the speed to 20 its freaks me out so much could you please guide me in the right direction please
It sounds stupid but the parking lights in my vehicle won't cut off after shutting off the vehicle. I was told that the grommet is worn out in the brake pedal and that has something to do with the power loss with the engine. It all just started happening at the same time. Could you corroborate this hypothesis. I have a hyundai sonata 2012 limited
Hey Jason. So how do you remove those catalytic converters sensors first off?
I saw your videos about bmw cars,
I have a big problem with my E46 BMW 316i automatic transmission engine n42b18a.
The car turns off when it is on minimum rmp of engine. (600-700rpm)
I have controlled sensors, MAF, MAP, air tubes, throttle sensor, I put a new chain, controlled ecentic sharf valvetronic, I changed electromotor of valvetronic and oil of engine is new. Everything works ok.
The problem is not solved yet.
When I check for errors on pc, shows only o2 sensor with error.
When I unplug the cable of valvetronic the problem fixes, but the car has so reduced power.
What I can do? Do you have any idea?
Thank you so much.
Have a nice day.
Xhei
I had a bad ccv and maf sensor. I replaced the maf sensor but i didnt do the ccv. Since i did maf sensor, the car shuts off at low rpms. I have a 03 330i. Is there any suggestion on this issue? Please respond if youre able too. Idk if fixing the ccv will fix this.
Thanks for another good tip !
Hi my BMW 318I 2004 E46 idles fine drives fine sounds fine Drives like a GEM BUT... As Im driving the engine goes into a limp mode doesnt go over 1000rpm's and doesnt go over 20kph. Then after a few seconds goes fine again. It does it sporadically it will do it every few seconds then wont do it for a few Ks Ive had 4 garages my icarsoft BMW scanner and a foxtell 301 and noone has found codes NO CODES at all. So Driving along fine cuts out to 1000rpm and 20kph doesnt stop or stall then it can take 2 seconds to 30 seconds to kick back into normal operation. COuld this be the catalytic convertors? Hope you still view this and can help with some advice. Thanks Ron @ Kiwi Exotics.
I’m having this problem. No check engine light but it turns off coming to a stop or slowing but now while driving. Changed the camp shaft & exhaust sensors but still having the problem.
Thank you
loss of power and misfires on bank 2 at high rpm/limited to 5k.. all general maintenance seals replaced and the fuel trims steady at idle along with 02 voltages although bank 1 post cat is .7 steady and bank 2 is between .58 and.7 volts fluctuating? I have tried moving around bank specific coils/sparks with no change, only misfires under high load cylinders 4 5 6.. Id say blocked cat for bank 2 header 😒
I have bmw e39 528i 2007 and im having problems of power loss from around 5000 rpm no faul codes nothing i have cats deleted long time before this happens do u have any idea what that could be?
I have e46 2004 with power lose and a triangle light illuminated on the dashboard plz help
any ideas for why my m52tu is getting bad gas milage ive chang... plugs ig coil ,s maf sensor cam sen crank pos sen vanos oil valve this is what i have done it has 119000 kilom...i,m the 3rd owner thanks very much
Hi from the uk my BMW X3 was parked up for some time and now down on power can you please help me.
Man plz answer my question. i bought 2.5 2003 automatic 2 weeks ago. 0-100 kmph is 11 seconda shown on obd2. its terrible. today we tested fuel pressure and it was 3.150 bars when engine was running at idle. can it be the reason ?
Hey Jason I'm a new BMW owner and my 2003 530i is running like crap when I start it or sometimes when driving. If I take these off so I drive around a bit with these connections off?
I have severe lose of power in my BMW 740, 2006. While scan with Computer it gave error for O2 sensors before catalyst converter. Any suggestion is highly appreciated
Where do you find the o2 sensor
I have headers what would that mean both o2 sensors on bank 2 though
Biggggg question to anyone who knows. What brand o2 sensors do y’all recommend me to use on my 330ci e46 ???? Need new sensors ASAP
This might of solved my problem on my 2007 e60
