Thanks a lot for information now I maybe able to complete the task at hand
Haha! I just got a 1990 corvette ZR1 has back fire only when decelerating. I was not feeling hopeful, up until the end of the video! I'll have to check tomorrow and see if it's the valves
Great video. I like the way you went through each step thoroughly. Engines are a SOB when there is a certain problem and you really have to go through a trouble shooting checklist just like that.
I thought you'd just take a stab in the dark and see if random stuff fixes things. Ah well, guess having a point might help, thanks genius. I'll remember that.
I have a continuous backfire on my throttle body injected 318 in my 1990 Dodge Ram while driving at cruising speeds, though I believe it’s caused by a rich fuel mixture due to a strong gas smell. Any ideas on how to diagnose/fix? Thanks!
Thank you so much for making this video. You actually help me fix my own car. Therefore saving me a ton of money 🚙💵💜
You are so welcome!
whats was your problem @joanneferguson7964 @@2carpros
Is it normal for pro charged vehicles as well? Specifically a 6 speed manual between gear changes
Just had 351 firing through carby under load in 4th gear down low RPM, vacuum line to the advance unit on the dizzy was old and loose, cut the line a little bit back and refit it back on and there you go, I don't know if it was the vac leak or the poor advance alone or a combination but there is no backfiring now
I have a Harley that backfired when it was brand new. It only started after I took the factory mufflers off. The small afterburn that I’ve heard in every Rx-7 that I owned, when I put the flow masters on my mustang, but the Harley (fuel injected) can sound just like a .45 shot if I take off wide open then let off.
Backfire is all fun and games until someone calls the cops thinking it's a gunshot... lol
Do a video for carbureted engines.
Great video
Thanks a million
My 2001 dodge ram 1500 6 cylinder is backfiring through the exhaust and dying at stop signs or when I put it in reverse it will start stuttering and sometimes backfires sometimes it runs perfect for a week or two and then it does it again usually when I put it in reverse it usually stops and runs right after I shut it off for awhile sometimes after a long drive when I slow down it starts popping out the exhaust
I replaced the valve timing solenoid in my 2001 toyota avalon and it runs much better. No misfiring and idles at 800 rpm. Check engine light and VCS lights are back on. Any suggestions??😊
.......Or change the engine .
Lol ! I’m joking!
Great video help me a lot thanks!
Thanks lads
I have 98 f150 with4.6 had diesel put in it and drove bout 100 ft I cleaned all of the tank out and new plugs but engine light is blinking and it back fires any ideals I know it's a misfire but I have no idea how to fix it ran like new before this crap
Great Vid good info
Glad it was helpful!
Thank you!
You bet!
On chevy 366 gas engine its always been a broken valve spring/ bent push rod or woren cam lobe.
Dear it happens sometime if your cam senser is not working properly or have adjustment is needed
video was very helpful
I have an 81 celica Supra 5m-e engine with auto transmission.
I get backfire out the pipe and cannot WOT over 4k RPM in neutral or in Drivewhat gives?
My family’s 2018 Dodge Durango R/T, when going up a hill, (15-20 degree angle) makes a slightly muffled sound, and then makes a very loud pop, would this be an issue with the valves? Let me know please :)
Thank for beautiful video thank 😊
So nice of you! Thanks for watching!
How bout on a car that has no computer or fuel injectors?
Thank you so much
No problem!
what a nice and very creative video is great favor keep cooking and keep safe
Thanks fro watching!
great video , i really appreciate it but now i know it can be soo many things damn , just gna leave it as it is now lol
Nissan patrol v6 back fire in the intek side what is problem bro please tell me Thanks
If fuel delivery fails, there isn't as much fuel as usual reaching the piston chamber. How then would the fuel mixture be rich?
It causes a lean condition on that scenario.
if the fuel pressure regulator fails you will have to much pressure at the injectors and it will run rich and use lots of fuel
Hi my 97 honda accord was working good .tried starting it on a cold day it started was warming up n it cut off.look under the hood antifreeze everywhere.started it today it started i cut it off tried to start it again and it popped under the bottom of the car.help
Lashone Harrison head gasket
What about carburetor engines that back fire. My 83 350 doesn't have a maf sensor.
When I came thru the ranks a long time ago, there were two causes ; lean mixture , or retarded timing , nowadays any number of things can cause these conditions, or give the ecm false information.
@@beckywatt5048 89 honda vt1100c anything over 1/8 throttle backfires thru carb n dies...any idea.. Been fighting this for a few months now ...
Redid the head gasket and the timing gear on the camshaft of a 2.5 L Chevy S10 1990 readjusted the valves everything should be timed in backfiring through the carburetor is there a step I missing check the distributor everything should is lined up any help any ideas of why it's backfiring and won't run
Timing Problem adjust the timing
It's got two timing gears one on the camshaft one on the crankshaft both of the shafts are keyed the camshaft is the bigger gear crankshaft being the smaller if bull timing marks are supposed to be lined up with key way then I shouldn't be out of time unless it's the crankshaft 180 degrees out right or wrong

I’m having a issue with my truck backfiring (like a cannon going off) each time I fill up. Does it about 4-5 times. I’ve only owned the truck for 3 weeks. It’s a 2018 F150 turbo charged 5.0. Any ideas?
I’m having the same issue with my 5.3. It sits there and idles, then starts backfiring
hello, we people did some major service of porsche cayenne V6 car, after
having the test drive everything was good as usual, but someone from
washing team sprayed water on car engine. Next day when we people come
to know about this we checked the car with scan tool. as engine light
was on and there were some misfiring codes & a crankshaft sensor
code(P0338), so we removed spark plugs& ignition coil, removed water
from there & checked the engine again.. Misfiring codes were gone,
at idling everything was o.k., but as we increased rpm engine light was
on again & it was also backfiring at high rpm..... checked scan tool
again, the crankshaft sensor( P0338), was there... we tried change MAF
sensor & throttle body, but no improvement.... what could be the
cause ??????
Look for rpm at manual and cheek sidle speed at specification
The car dried and vicky started it back up over a year ago.
Hey can you help me out i have a 1987 mustang gt am having backfiring problems low power low temp i changed spark plugs & wires, distributor ,fuel filter and am still having problems
Adjust Ignition timing if adjustable.
Good luck.
Distributor ignition timing.
'88 Silverado somebody fixed it recently fixed it and now it's back firing it has never ever done it before.
Also worn cam lobes and cam caps.
Mine hit the rev limiter and backs fire at wot?
Great video
Question I have a 2007 v8 5.4 I recently replaced all plugs but used same coils. Now it backfires when it’s cold when I’m accelerating . Also when I get outside and touch the body it zaps me !
Any ideas ?
Check all your ground connections and the wires running from the coils for any imperfections
@@luispichardo6704 im kind of thinking that comment was ironic
Does anybody know why a 1998 Ford ranger would be backfiring threw the breather
How does a low preassure causes a backfire!? Regardless the explossion should happen i side the cylinder..it will cause a missfire but not a backfire..if im wrong please explaine
no problem, if the fuel mixture is lean (not enough fuel) and the engine is under load it will backfire through the throttle body.
SANTA MUERTE
My truck is not just backfiring it is stalling and now it won't start at all we have taken it to a shop and he said he checked everything he replaced the ignition module a couple of other parts because he could not figure out what was wrong with the truck the check engine light was not on so we could not scan it. This truck has a lot of power so some of what your video shows makes a lot of sense but the stalling and almost dying on the freeway twice plus the backfire..?
i tried starting,my engine multiple times after water got in the oil. i changed spark plugs 6/8 and oil change as well and left it for about 3 weeks. i went to start my engine again but i sprayed starting fluid in the throttle then that's when the popping happened. could it be unburned fuel stuck on spark plugs or just too much starting fluid?
Same thing happened to me change all the spark plugs and if u sucked water through the intake like I did change the intake temperature sensor and the mass airflow sensor
I just put water down the snorkel bit and now it definitely won't start.
Do I put a match in the petrol tank to check out if that will help?
Take the spark plugs out, crank the engine over once or twice. Then change the oil. Thanks for watching!
@@2carpros no worries...
EJ20 - head is O ringed not the block, 2mm copper head gasket. Any special advice? apart from being especially careful around the water jackets with the exhaust sealant..
@American I liked their reply. I'm assuming some understand the humour, bit of the ole Month Python sort of jibber jabber. They know what o-ringing a block is, and how to check leaks. It gets messy... Lol.
🤣 You’d make a fortune setting up shop in my south Florida neighborhood .
Love visiting Florida! Thanks for watching!
@@2carpros This backfiring trend is getting pretty annoying, it sounds like a battlefield on the weekends lol
Actually, backfiring at the rear exhaust is a good thing....cuz it sounds cool.
🤣😂
no thanks
I heard to never use carb cleaner on it.
we have an RV we are trying to get going again. It cranks but backfires inside the engine, and will not stay running. It is a 460 engine.Its a Ford econoline 350. 1991.It will not idle at all. you have to keep pumping the pedal. i know its getting gas but as soon as you let off the gas it dies.
Adjust your carb
I have a frustrating problem on a '91 Olds 98 Regency (3800)...... It backfires when the engine is cold and when it warms up it runs fine....... I have replaced wires, plugs, coils, ignition module AND Temp sensor........... what else?
That is a complicated question, if you go to our website www.2carpros.com and ask a question for free, an expert will be along shortly to help! Thanks for watching!
But what happens if you dont have obd2?
If you don't have OBDII, you're probably mechanically inclined and can figure it out yourself. These guys can't do anything without the computer telling them what's wrong and what to do next.
I cant scan mine its an b18b swapped from an integra to a civic.

My friend said thank you
Tell your friend I say thanks for watching!
Do you have any idea on what could cause a 2005 mustang gt to backfire really loud at idle? I have new sparkplugs, coils, and injectors.. also have one bank running rich and the other lean
I’m experiencing this on the same car, I have a replaced engine have you found the problem?
@@goofy1496 yeah, my issue was a broken valve spring
Hi I have 2006 LS motor 6.0 I get blow back through the carburetor I change the cam I put a 6:22 in it can you help me
Your LS has a carb? Did you convert it? Thanks for watching!
Yes yes I did converted thank you
@@lazp7953 what an idiot why in the hell would you carb an LS what a waste.
I have been having some car issues can you help me try to pinpoint what's going on
Idiot
yeah take it to a mechanic
Lmao thats what the video is for?
My mazda 3,backfires on idle and on low speed jackup like it's cutting power on and off.
so basically for my exhaust backfire. i should just have a leak right?
Nope
my 351wensler oilpump went out ifixt it and it will idle great it spits when I give it gas what is that could it be my timming chain
Yeah I had that problem with my 351W Bronco and it ended up being the timing.
Ok thanks
Ronald Latham spits where
Okay okay okay thank you
So a small evap leak will cause a car to backfire?
My car golf4 gti if Engen running is buckfire
I need fix back fire what should I do
f150 rough idle ,back fire and really high idle.
Sounds like you have a vacuum .
Same!
The problem is circled in blue on your grill.
Same on a 2002 pontiac grand prix replaced all vaccum lines
Oh your good bro thanks a lot, you save my ass.❤
Happy to help!
I just replaced the coils and plugs on my 2003 hyundai sonata and the cylinder backfires when I attempt to accelerate or rev the engine in P/N. I ran a diagnostic on my OBD2 scanner and it threw a p1166 code so I have a bad o2 sensor. Could that cause a backfire? Or maybe the spark plugs or coils were incorrectly placed?
I would definitely change that O2 sensor then see if it still backfires. Thanks for watching!
Was it the 02 sensor?
If your find whats wrong with your carburetor you cant use a scan tool. Im trying to find whats wrong with my 73 C-10 350
DO NOT use carb cleaner on a MAF! There is a specific MAF cleaner available which will not damage the components of a MAF. Carb cleaner is too strong!
Carb cleaner and MAF cleaner are very very similar and do that same job. We have been using carb cleaner for nearly 20 years with no problems. Thank you for watching!
Guess again! They are NOT chemically the same. Carb cleaner has a much higher percentage of Toluene, which is very destructive to plastics and electrical components.I have seen a friend ruin his MAF through the use of carb cleaner. The plastic housing inside disintegrated!
Erik G. T
Yes I agree never use carby cleaner or brake cleaner , I've see countless times people using these and completely destroying MAF's had this argument with an old timer at work and we actually tested it on some spare sensors we had laying around all of his sensors failed , I used the correct cleaner and all mine still worked
Great video though guys
Thank Eric as I was watching I was thinking the same thing, had to look through the comments first and sure enough .🙂
Yes I drove my keep for about two weeks and now it just backfires through the carb what can cause this?
Dusty Reuchenbach Timing may be off. or you could have bent valves
Dusty Reuchenbach
Dusty Reuchenbach I have a 97 dodge dakota driving down the road , the engine will cut off. Then it will start again. While moving. Has new fuel pump
fuel filter ?
+Lee Coleman faulty coil? fuel filter? did you find out what the problem was? my 91 mighty max does this
My problem was a stuck valve..... Caused backfire while driving
Backfire from carb
Oh that is interesting! Thanks for watching!
I have exhaust backfire only when i release the throttle. If i acclerate steady it goes smooth. Let off and i get LOUD popping, especially driving over 45mph. Idle is smooth. 98 dodge ram 5.9 gas
same problem here on my 93 miata, any fix ?
@@JAPerror my timing was off. I rotated the distributor a few degrees and it runs smooth.
I have o3 tracker
Is it a reasonable conclusion that oil leaking onto one or more spark plugs will cause an intake backfire
No that will not cause a backfire, A little oil can accumulate which is normal but it can mean the valve cover is leaking.
@@2carpros a leak in valve cover will cause a intake manifold backfire?
Could bad 02 sensors cause backfiring and cause the car to cut off
Sounds more like bad plugs and/or coils. Thanks for watching!
Bad Crankshaft or camshaft position sensor can make your car cut off while driving. Bad O2 sensor will make your car run lean or rich.
I am getting bang sound only one time at the time of cold start
have same issue lately
Thats a great viral video idea... making a plastic intake explode with 2 step... *you're welcome*
Hello everyone, this is your daily dose of internet.
Thanks for watching! Later!
My van runs good till in gets warm then it miss fire's bad
Spark plug wires clearing the headers?
You Mean when tolerances become worn. Good video but think about how designs should work and wear and tear on tolerances .
Right on! Very important. Small but good example was maintaining shotcrete machine underground mining and the tolerances were fked. Alot of guys couldn't run machine the shitrete was too thick or too thin and the gun operator was always saying too thin mix too thick. Instead of constantly setting concrete mix and air pressure I just kept constant preddure on grease gun as the shaft and bore turned making it constant. Other operators were fighting worn tolerance and trumng to set up constantly between but with great gun it kept it all in one. No problem. Understand the machine, steel and tolerances . Right on!!!
I have an 82 E150 no codes on these vehicles.
Yes there is
@@wyohorseman9948 try and find an obd to cjeck it
My car shakes when I press the pedal slightly then it pops
I'd service the throttle body. Thanks for watching!
Most people wouldnt like to fix it and im just like whats wrong with you
Agreed! Thanks for watching!
Uhh people dont want to fix the popping from the exhaust pipe, cuz its awesome.
5:05 Wtf dude you scratch it 😮😅
damn nice catch
Check the computer codes!!?? My 1983 Chevy C10 doesn't have any stinkin computer codes! Lol
By
14:7:1 is the ratio
My motorcycle is starting properly and ilding properly but when I open the throttle my bike backfires and die.
And one more thing that my bike is not starting with an open throttle, it just starts with closed throttle
Why would you want to fix backfiring? i would rather have my engine backfire constantly tbh
It's pretty hard on the engine and exhaust system not to mention loss of power and economy. Thanks for watching!
Hayes repair manual don't mention plugs as cause of back fire. but I don't care so much for Hayes manuals. misleading I.m.o.
What? Cleaning a mass air flow sensor with carburetor cleaner will destroy the mass air flow sensor!!!, it’s a specialty cleaner for mass sensors cost twice but will not destroy your sensor.
Shyt wears out.
Why would you fix that? Lol😂
01 F150backfires
Nobody
yup idk lmao
👆🏁🤘
just keep the backfire
It says in 15 minutes but the video is only 10 minutes
The job would take about 15 minutes in real life. Thank you for watching!
Smh
WHY THE HECK WOULD ANYBODY WANT TO FIX A BACKFIRE?!
Well rolling up to drop your kids off at kindergarten isnt very cool.
Because more often than not a Backfire is accompanied by loss of power from the engine. Not Good. 😕.
Your just quoting word for word someone else's diagnosis
no use to me
Thanks bud.
that did not help me at all, might by a whole new car
