Just wanted to say I cannot believe how easy this was, I had thus issue with my 07, and did this, and it runs smoother than ever! Thank you for saving me money, because I was about to put it in the shop.
Awesome teaching...just remember not to open the throttle plate with our hands....switch the key on.not start..then someone press the accelerator to the floor. Until the plate opens
HI, GOOD VIDEO, I WOULD JUST LIKE TO ADD THAT I AM A PRO MYSELF AND HAVE FOUND THAT WHEN I SPRAY THAT MUCH THROTTLE BODY CLEANER I HAVE RUN INTO HYDRO LOCK TROUBLE, I HELD THE THROTTLE BODY OPEN WITH THE ENGINE OFF FOR ABOUT TEN MINUTES TO ALLOW THE CLEANER TO EVAPORATE THANKS IF YOU READ THIS
I just followed the video and right after I put her back together, I fired her up and she shook like a dog, smoked my whole driveway up. I raved the engine 1 time and then it idled like a champ. I wish I kept the flow open for a few minutes now.
Just had a friend come to me with rough idle/stalling. As it has over 200,000 miles on it I decided to check a few things before assuming anything. Turns out the spark plugs were Way Past due to be replaced (gap was nearly .80 instead of .42) And they were the wrong plugs. Almost 1/2” short!!! In addition I found a vacuum leak and an intermittent coil pack. Runs like a bandit now! So, before getting knee deep in a repair always verify the simple stuff.
Great job nice DIY video.. My car would shut off when I turn on the AC.. and this was exactly the problem.. it started when I had removed my battery plugs to replace my stereo to an aftermarket.. The car started fine afterwards and idle good but I went to turn on the AC and it started jumpin a bit after 2-3 times it would shut off.. at first I thought I wired something wrong so I switched the radio back to OEM.. but the same problem kept arising.. turns out the CPU was reading dirty throttle.. this helped so much and saved me money.. Thanks!!
You should never push open a throttle body! Doing this can damage the electric motor that opens it when the accelerator pedal is pushed. Instead, have a helper turn the key to ON without starting the engine, and hold the pedal down or use a heavy object to do so.
Removing it is the best way to get the job done because you can access all parts of the throttle blade and body. But you really don't need to do this every time you clean it. Once you have removed it and done a thorough cleaning, if you keep up with regular maintenance type cleaning it should not be necessary to remove it every time.
@@freedomdiggersmetaldetecti8964 I bought your old Chevy suburban a blue '93. It had a big sticker on the back window with your screen name on it. It also had a trophy buck hunter sticker.
my trailblazer was shuting down while driving, so I cleaned my throttle body but I didnt spray like crazy in this video. mo more stalling but my engine light is still on. im very happy that cleaning the throttle body this way helped. i think i just have to get the light reset with a code reader or whatever. i found out u shouldnt just disconnect the battry in trailblazers to reset the light. anyway thanks for the guide.
Thanx for the video. I recently had an issue with my horn, it didn't work. Did some youtubing to fix the the problem and was told to disconnect the battery so the airbag would not go off. No problem, made repairs , horn works. Just one problem, rough idle when i put the air on to the point that it stalled every time. Disconnected battery and reconnected to see if the problem would rectify itself, no dice. Anyway, i read one of your viewers comment and he was changing a speaker system and disconnected his battery and he also got the issue i had. But for chicks and giggles he took your advice and cleaned out the throttle box and it worked! I could only hypothesize that the throttle box butterfly must go into deep closure scraping excess carbons and creating a build up at the inner circumference wall. As i see it. Sorry for the long explanation, hope it helps. Peace
I have an 03 that has had a rough idle for years. I Replaced the throttle body, the coils, harmonic balance, spark plugs, intake gaskets , all the evap sensors, transmission mount, and tuned it up. And still a rough idle. Finally I’m going to change the fuel rail and injection. I hope that helps. If not I’m sending it to pick a part.
My 05 trailblazer was idolizing a lil rough so I’ll take ur advise and clean my throttle botty tomorrow and see if that solves the problem. Im convinced it’s the problem. Thank you in advance
Take the throttle body off to fully clean it. Not sure what "problems" he could be referring to. It is unhooking on connector, 1 hose and 4 bolts that are all easy to get to. To get it really clean you will need something like a tooth brush to really get all the carbon off. It takes maybe 5-10 extra minutes but it will look brand new and work much better. The back side of the throttle body will look much much dirtier than the front.
The ERRATIC IDLE - Replaced the Throttle Body and did a Relearn - No issues this one had never been cleaned and works like a champ now. Depends on the condition of the throttle body - in my case replacing was best solution.
Hi bro I have the same problem on my chevtrilblazer I have changed everything to get the service engine light of but I haven't done this before I will try this thanks for the advice on this this is a great channel 😀
Thanks. One point opening the throttle plate by hand is ok but don't open it too much and don't let it slam shut this can change the air gap in the plate n throttle body Good info on your post.
It could be solenoid vvt, oxygen, crankshft or camshaft sensor. Replaced everything and found out my sensors were bad. Throttle body was first thing I replaced. 2004 trailblazer. I looked up 10 top problems with first generation trailblazers.
Hi, thanks for the video... I have a '02 Chevy Trailblazer and she have some rough idle problems and whilst driving, the motor seems to dip.... No engine light on... Also connected my OBDII reader, and no codes.... I'll give the cleaning of the throttle body a go...
my wife is yelling down my throat 🤦🏽♂️🤦🏽♂️🤦🏽♂️🤦🏽♂️ I spent for a like new engine, 93 thousand miles and the mechanic said it was done, got back my 05 Chevy trailblazer back and a couple days later, I tried backing up and the gears were slipping like it wasn't snapping in the gear and then it shut off like if it was in neutral. Now It wont rurn back on fuuuuuuuuuk!. Its acting like a bad battery or starter but I just got the battery. I am calling him tomorrow to see what the hell is going on, I dont have money to just throw away, people are struggling u kno, what do or can I do I am lost right now here ?????🤦🏽♂️🤦🏽♂️🤦🏽♂️🤷🏽♂️🤷🏽♂️🤷🏽♂️🤷🏽♂️
Im going to get to cleaning mine soon if i was to have to change a sensor out would it be better to change the whole throttle body out or could i get by with just the position sensor
I just bought my 2004 Envoy knowing it would need some work. After taking a 600 mile trip it started running rough and would often stall at red lights. Then I noticed as I was traveling at the posted 45mph speed the engine was accelerating to 45 and then coasting to about 42-43mph, and then back again. A mechanic suggested I start by cleaning the throttle body. Then I found that the fuse box under the hood had been burnt. Both solid state relays were ruined and a couple mini relays were welded together, and many others looked to be in bad shape. I've replaced all of that - the box and most of the relays and fuses. Sounded bad when I restarted the engine. My code said that the 3rd cylinder (4.2 I6) was misfiring. So I replaced that coil pack and all the spark plugs. Sounds worse now. My code said the 3rd cylinder (4.2 I6) was misfiring. I replaced that coil pack and all the spark plugs. The new code from the scanner says 'Random / Multiple Cylinder Misfiring Detected'. I think my SUV will need to do more than just relearn how to idle. Please help.
My 07 Chevy trailblazer is not going into overdrive it'll shift fine in first second third but sometimes it don't want to go into overdrive I don't know why is it the computer or is it my transmission do you have any information on that please tell me thank you from Oklahoma City
I had the same problem and i did clean the throttle body and it worked. But i should say that u shoyld take the throttle body off and clean it real good. Because sprayng all that cleaner while its on will blow back into the engine and u will have bigger problems...
Hey my auto mechanic, do you know where I can purchase an inexpensive code reader? I also have a 2006 Chevy Trailblazer and it is currently having the same exact issue. I noticed in this video that you disconnected the battery to reset the idling, unfortunately this will not reset the check engine light. I really appreciate this thorough video, in fact, it is the best one yet when it comes to this specific problem. I have spent $1500 thus far with "tune ups" and "number 1 misfire codes" , according to my mechanic. I'm usually the drop the car off to get it fixed kind of woman until my Chevy Traverse started having problems. I will let you know how this turns out after working on both vehicles this weekend, as I have become a more "Do It Yourself" kind of woman. Thanks again for this dummy proof video.
Replaced MAF sensor, Trailblazer went into Reduced Power Mode, threw codes for MAP Sensor, then threw P0506. though I cleaned the Throttle Body several months ago. TB had 134k when I bought it, now has 168k
Heres my question...i have a 08 i adore my tb so much but its been threw the ringer. Im trying to be better to my girl now a days. So i find it wierd that the temp is ALWAYS on 100, Never gos up. Do you have any suggestions. thats just one I HAVE MILLIONS lol, hope you Respond. I just found your channel, THANK YOU
@@bandittweintraub essentially yes they are slight differences biggest being the upgrade to the 4.2 early ones took 7qts and made like like 275hp the later ones were 295-300hp and a 6qt engine
I understand that you should never manually open or close the throttle body when cleaning or, use Carb cleaner which removes the coating on the inside of it. Stepper motor damage etc, when moving it manually or with key On. Sometimes you have to remove fuses under the hood #10 and #28 for 15 minutes to get TBSensor to reset.
Hi Gord Baker, I have a 2003 trailblazer by mistake I did exactly what you said not to do ,I moved the throttle body manually to clean it and yes after that a start it engine , it had a rough idle not to bad , do I have to replace the throttle body? Thanks
i did the same thing on my 2003 trailblazer i clean the a throttle body and did the a reset too but still gives me a rough idle and when the AC is on sometimes at shakes and at shuts off I change the a fun clutch too
Bad Coil it's misfiring my Trailblazer did that go down the road the check engine light would flash off and on plus my Cruise Control would not work scanned it was #2 coil changed it the light stayed off and cruise control worked again
So removing both battery cables fir an hour should dump memory of old idle positions and reset to new one without having to remove any fuses like I’ve seen in other videos for same problems
Nice ..... I couldn't die for the subscribe button quick enough also I did a thumbs up and I'll clean out my throttle body on my 2005 Chevy trailblazer with 147,000 miles on it I've got a question though how do you put a Chevy trailblazer in neutral say if you run out of gas because I couldn't put mine in neutral when it wouldn't start and I just bought it
Thanks for the info..my envoy 2006 is stalling out after it get hot. I had it feeling it has something to do with the throttle body. Let you know after I clean it.
I have a 2005 Chevy Trailblazer 2.4L 2WD. I had a very rough idle condition and replaced the camshaft sensor, crankshaft sensor, spark plugs, variable valve timing solenoid, air filter, spark plugs, cleaned the throttle body, and replaced all of the coils. It took car of the rough idle when I replaced the coils, but now I get a stall condition with no rough idle when idling at a light on occasion. There are no codes, they all went away. Should I replace the MAP sensor?
I did all you showed , but forgot to disconnect the battery and reset the idle. I still have the rough idle, should I reset by disconnecting the battery?
I have a question for you my 2007 Chevy it flutters when you give it the gas if a trailblazer and has no get-up-and-go it has no takeoff power I think it's transmission but then I don't know it could be the I've cleaned the throttle body on the outside not the inside in other words I did not take it off to clean the inside what else could be wrong with it plugs ROK I believe everything's all right for now thank you for time.
Hey I'm working on a 2004 Buick it has the same motor as a trailblazer in this video that you just did and I cleaned out the throttle body I've replayed I've replaced it and I cleaned it out and I'm still having a horrible idol issue I don't know what else that I can do to maybe to solve my problem can you help me
Question ❓ how does moisture get underneath the coil top in the number 6 . I have a 2003 Chevy trailblazer V6 4wd ls. My other question is during these very cold mornings I hear a strange noise that lasts about a minute or two and only does it on very cold mornings.
I usually remove the throttle body to clean both sides.Try not to move thst butterfly ,the vehicle might take a few days to relearn the thrittle secuence.
I have an 03 trailblazer. I replace the throttlebody the air filter and a lot of other things under the hood. I’ve even added a K & N Exhaust kit to the fix. My idol is still low. I’ve changed gas filters and everything else they have to do with gas. No none of this is making any sense
What you got on coil packs? I've replaced certain ones multiple times. Check engine light still on, runs a little rough too. I am going to clean throttle body. Any issues with plugs and packs causing check engine light? Great video, thanks for taking the time for DIY home guys
I'm working on an 05 trailblazer. It has the reduced power light on which is the engine with a down arrow in it. Not sure if the catalytic converter will cause this problem or something else. I checked fuses, they are all good, but it definitely runs rough, and is completely under powered. It won't even rev up even a little bit. Any suggestions would be great, thank you!
Thanks that was a big help I have a question I have the same truck 2003 truck runs well comes on fine but it all of a sudden stop iddleing when I press on gas no movement of idle put in drive doesn't move can u answer me back
I thought spraying in the throttle body like that could risk hydro lock and also the learning of the throttle position since there is no accelerator cable?
My trailblazer vibrates at idle more in drive but still in park. I cleaned the throttle body, replaced all ignition coils and spark plugs, changed air filter and it still does it
I have a trailblazer, it’s rough at idle then dies smells nasty to. I cleaned the throttle body still has the issue. Do you have any tips you can share ???
hey but you suppose to remove the TB and clean it on a safe place no still attached to the engine, all the debri will go to the combustion chambers in the cylinders!
Hi I have a 2003 envoy when the ac is on and come to stop signs it idles rough and sometimes turns off I already cleaned the throttle good and still does it?
i chanģed battery on my 04 trailblazer. and since then it stalls at redlight or when i turn heater blower on, the idle rumbles and almost stalls. spark plugs are new. battery new. so i am going to clean my throttle . if its not throttle, what else could cause this idle issue. it all started after battery was disconnected
Great video. I have a 2000 Ford Taurus Duratec Engine. Engine light was not on but I got a smog check and was told car did not pass due to engine code P0506. After the smog check the engine light is now on. Funny thing is the tachometer says the car is idyling at 900 rpm which indicates to me the car is not idyling too slow. So, how could the computer think it is idyling too slow? What could be causing this code?
Just wanted to say I cannot believe how easy this was, I had thus issue with my 07, and did this, and it runs smoother than ever! Thank you for saving me money, because I was about to put it in the shop.

Take the throttle body off to fully clean it. Not sure what "problems" he could be referring to. It is unhooking on connector, 1 hose and 4 bolts that are all easy to get to. To get it really clean you will need something like a tooth brush to really get all the carbon off. It takes maybe 5-10 extra minutes but it will look brand new and work much better.

Question ❓ how does moisture get underneath the coil top in the number 6 . I have a 2003 Chevy trailblazer V6 4wd ls. My other question is during these very cold mornings I hear a strange noise that lasts about a minute or two and only does it on very cold mornings.
I usually remove the throttle body to clean both sides.Try not to move thst butterfly ,the vehicle might take a few days to relearn the thrittle secuence.
Cured my problem ,thanks for info.
Dat was splendid job. It definitely worked for me. Thank u 🙏
Thanks for winderful vid..
Kindly guide how to get rid of engine maintenance light??If it still remain after throttle body cleaned.thanks
Awesome!!! Worked perfect!!! Thank you!!!
Could be wrong...but I thought you weren't supposed to move the butterfly that much
I have an 03 trailblazer. I replace the throttlebody the air filter and a lot of other things under the hood. I’ve even added a K & N Exhaust kit to the fix. My idol is still low. I’ve changed gas filters and everything else they have to do with gas. No none of this is making any sense
Did you figure out the problem ?
Thanks for informative video showing us how to do this job.... I appreciate the hiw to lesson. 👍
What you got on coil packs? I've replaced certain ones multiple times. Check engine light still on, runs a little rough too. I am going to clean throttle body. Any issues with plugs and packs causing check engine light? Great video, thanks for taking the time for DIY home guys
2004 trailblazer LT, 145k miles
I'm working on an 05 trailblazer. It has the reduced power light on which is the engine with a down arrow in it. Not sure if the catalytic converter will cause this problem or something else. I checked fuses, they are all good, but it definitely runs rough, and is completely under powered. It won't even rev up even a little bit. Any suggestions would be great, thank you!
I had that and it was the throttle body. I took it off and cleaned it thoroughly and it fixed the issue
Thanks that was a big help I have a question I have the same truck 2003 truck runs well comes on fine but it all of a sudden stop iddleing when I press on gas no movement of idle put in drive doesn't move can u answer me back
Worked perfectly, thank you!
I thought spraying in the throttle body like that could risk hydro lock and also the learning of the throttle position since there is no accelerator cable?
My mechanic turned me on to ur page thank him too lol
My trailblazer vibrates at idle more in drive but still in park. I cleaned the throttle body, replaced all ignition coils and spark plugs, changed air filter and it still does it
loose motor mounts have been known to cause this problem according to my research...hope this helps
Can you say "throttle body” just one more time please 😂
I have a trailblazer, it’s rough at idle then dies smells nasty to. I cleaned the throttle body still has the issue. Do you have any tips you can share ???
hey but you suppose to remove the TB and clean it on a safe place no still attached to the engine, all the debri will go to the combustion chambers in the cylinders!
Hi I have a 2003 envoy when the ac is on and come to stop signs it idles rough and sometimes turns off I already cleaned the throttle good and still does it?
I noticed that when I pulled the air box off there was some fuel inside. Where is it coming from?
I disconnected the battery terminals after cleaning, is that an issue?
i chanģed battery on my 04 trailblazer. and since then it stalls at redlight or when i turn heater blower on, the idle rumbles and almost stalls. spark plugs are new. battery new. so i am going to clean my throttle .
if its not throttle, what else could cause this idle issue. it all started after battery was disconnected
I had an alternator replaced and removal of battery cables caused one of the actuators in my a/C to fail. I don't wanna go through that again
If the throttle body is not removed, wouldn't the engine suck in the crud and soil particles when it is started?
Do I disconnect before I clean the throttle body or after...? The battery post I mean
Hi... Eric in Detroit and I'm having a rough idle problem with a trailblazer I just purchased. It has 154071 miles
I Have A 05 Trailblazer And It Shakes When I Run It Up Any Thoughts Please ?I Need Help
Put your seat belt on 👍🏾
Thank you for your helpful video.
I have a 2004 trailblazer and it runs ideleslower then it should did all you did and still is rough
You didn't mention to reconnect the vacuum line at the front left side of the air box. Not good if you forget!
Thanks for your help really knowledgeable
Great video. I have a 2000 Ford Taurus Duratec Engine. Engine light was not on but I got a smog check and was told car did not pass due to engine code P0506. After the smog check the engine light is now on. Funny thing is the tachometer says the car is idyling at 900 rpm which indicates to me the car is not idyling too slow. So, how could the computer think it is idyling too slow? What could be causing this code?
I'm guessing you junked the car by now. Don't know why there's no responses.
Anyhow I really suspect your problem was a fouled EGR valve.
