Great video! I just replaced the alternator on my 2004 Envoy. It is still idling a little rough and hope that cleaning the TB helps out. These SUVs are solid! Had mind for 17 years.
I had a rough idle on my 06 and this made all the difference in the world. So much so that I thought the engine died every time I came to a stoplight. Nope , just super smooth.
Great video. Really helped me figure some things out. Keep up the good work. Thanks.
Your videos are awesome. Saved me lots of time, frustration and money.
Oh and by the way I love the way you show your videos you do detail for detail you're awesome thank you so much for sharing these videos I learned a lot
Nice touch taking the plate off. I'll do THAT as soon as I get the TB off. Thanks..!
Glad to find a envoy as I have one and very informative
This video just gave me the courage to clean mime. Thank you.
Great video training, thx Kenny !!
Man you are a god send! Ive been looking for videos for the longest on how to work on my envoy. Took it to a shop and eas told it would cost me 800 buck to do a tune up .
Super helpful bro thanks 🙏🏽
I'm usually not a fan of background music but this video was different. I actually enjoyed it. Good tutorial man. Keep it up. Just bought a 02 Envoy 4x4 I'm about to fix up for my new daily.
Thank you for the video it was a big help
It is so easy to do I clean mine 2007 trailblazer 208000 miles, after each oil change. Almost like a little tune up. If you have fat fingers like me may I suggest a magnet wand. Cleaned mine today and sure enough dropped one of the resonator bolts down in the frame😂
Thank you for this video. Excellent!
Literally glad!! There is someone showing the same suv I have very informative and helped a lot!! Thanks keep up the good work definitely a sub
Thanks
Good stuff brother worked for my 2004 gmc envoy xl thanks
Keep on making videos! You will grow, I promise! Love your videos
Thanks man!
You do very good tutorial videos. I personally lern and apply your tecnic with efectice results. Thanks!!
You welcome
thanks for the help Kenny
Helpful video, I have an 03 Trailblazer. Nice music!
Great video. Thank you.
Taking the plate off... Dang i didn't think of that. I love the background music selection
Great video. I just bought a 2003 Envoy with "only" 154k miles on it. Been running a little rough and I'm planning on getting under the hood this weekend to do this, and a few other things. Doesn't look nearly as difficult as I expected.
Thanks for the video, I'm going to check mine out tomorrow to see how it looks. I've got a check engine light so cleaning couldn't hurt.
Hey what's up buddy I like the video and help me out a lot my truck was bogging out when it came to a complete stop at a red light or a stop sign so I ended up doing the same thing as you did in this video and my truck is actually running as new as could be thank you bro. 🙏🏻💪🏻
You welcome glad it helped.
Little things make the difference
Thanks for your tips...
You welcome
Thanks Bro Amazing. Keep videos coming. They truly help a lot

Cool tunes Bro,. Thanks for the info... Peace
the best explained video i seen so far thanks Kenny..i wasnt sure about the battery being disconnected and screwing up the computer..i got a 2006 trailblazer that needs to be cleaned.
Thanks glad I could help
Good videos 👍 keep doing more...helps time to solve problems... and we learn from your videos .. thanks...I have problem with back door... always lock...I saw one video were I can open from inside.... little hole...but can't get the door unlocked 🔓 or open... thanks once again...my envoy 2004
Great video
Great work. Im doing mine today on my 2003 GMC Envoy 4.2. I've heard you can use carburetor cleaner to clean it as well.
Thanks for the vid ! All meat no fat . Like my women ! Lol. Bought an 07 a year ago . Realy happy with it. Just hit 170,000. So nocking out the issuses as they come. Thanks for the content and great sound track !
Thanks
i use the SEAFOAM spray can to clean mine for a quick at the moment fix.
I would have liked to see the startup and hear how it runs compared to mine.
Otherwise awesome vid, great music, thank you!
I basically performed the same task but left the battery cables connected on my daughters 2006 GMC Envoy. It started right up and the old low rough idle was gone! I am about to perform the same service on my 2012 GMC Sierra 1500, it has the same rough low idle issue...fingers crossed.
Good job, did you have to reset the trhottle bory? After sin your video I'm going to clean up my trhottle bory?? Thanks
Nice video I used to clean my 03 as well as to tighten up my throttle body when I got a vacuum leak a few months later. Thank you.
Hey Kenny just bought a used Chevy trailblazer going to follow tips to do tune up myself wanted to say thank you for the video I am having terrible with the blower for the heat and Ac can you give me some direction please and thank you
What is wrong with the heat? What does it do or not do?
Tooth brush works great
I'm down with the music mixed in. Made watching DYI videos entertaining. COOL!
Thanks
@@GrimeTimeWithKenny Removed and cleaned and WOW the difference it made. One issue I did find. I'm getting oil in the (?) intake breather box (?) on a 2004 gmc envoy. Any suggestions? Doesn't seem to have a pcv at all.
Yeah they dont have Pcvs. I've seen alot of people having the same issue. Mine had a little bit of oil in it also. Honestly IDK if anyone has a fix for it.
@@GrimeTimeWithKenny I found a couple of videos. If ok I'll share or tag you in them.
@@GrimeTimeWithKenny th-cam.com/video/5xj3cRlykmw/w-d-xo.html
Thanks for the video. My 03 4.2 just started showing P0510 code which is "closed throttle positioning switch" I think I have to remove the throttle body and clean it thoroughly and see if it does the trick. Do I really have to reset the PCM after?
Just disconnect the battery for 30 minutes to reset it
Thank you I will be cleaning mine tomorrow .. I was hoping you’d show how she was running after
You welcome. Yea alot of people has said that. Honestly I didnt think of it at the time.
@@GrimeTimeWithKenny I cleaned out mine and so far so good 😊
Kenny, thanks for the demonstration video! Most recently my trailblazers been running pretty rough, and when I turned on the air conditioner the vehicle almost died. I replace two spark plug coils last week that were having some misfire issues I thought that was going to take care of it but it did not. I'm definitely going to give this a try!
did the coil packs throw a code?
@@innovativeintelligence4172 I'm not sure?, I had that work done at my local mechanic shop. They're pretty thorough, so I'm sure they checked that.
Happened to mine as well your compressor might be dead.
Did this today man thanks for the vid. Didn’t end up taking the whole throttle valve out just hosed down a towel with cleaner and wiped the inside and the flap and around the inside of it for now. Running a lot better. Was having low rpm problems when in park and when just idled at a stop. Plan on taking the whole thing off next time I’m off and doing a thorough clean like u did. Also changed the plugs. Noticed the first plug and coil pack wer pretty jacked up but the rest wer fine have u seen that before?
Yw
say, did this change the slow throttle response at all ??
When you disconnected the negative terminal did u also disconnect the positive? In another forum a guy said not to disconnect the battery
I just disconnected the negative
How do we knoq that worked since you didnt start the car adtwr the fix..
Reprogramming , do I need a computer on a 2008 trail blazer or will removing negative battery wire for 30 min work just fine .
Removing the negative cable will only reset the parameters it wont reprogram it
Hey I Gotta Question My 02 Envoy Won't Go Past 20mph What Would You Think Is Wrong Do I Need To Clean Fuel Injectors Nd Sensors ....?
It could be alot of different issues. Could be a transmission issue not shifting or in limp mode. Could be a timing issue like the camshaft position solenoid and sensor or fuel issue. I even seen one that had a bad fan clutch and it would cause it have trouble accelerating. Or could be worn internals in the engine.
Thank you for the help bud. Good video. I was going to warn you about your skin / throttle body cleaner. How do I tell if the issue is the pedal or the TB?
You welcome! If it was the pedal you wouldn't have any throttle response at all.
Hi can this throttle body if dirty. Will it cause u to loose power driving ? Because my GMC envoy 2002 drives slow and won't pull up the hills.slows down.I think the throttle is dirty
I'm experiencing the same issues. I've read in some cases it does. That's why I cleaned mine but it didnt fix the problem but didnt hurt to do it. It has better throttle response now and idles smoother! I've also heard a bad fan clutch can cause these issues. Which mine is bad and stuck engaged so that's my next move.
Doing mine tomorrow first timer lol
Awesome its not a hard job should go smooth.
Wish I could bring my truck to you!!!
Great Videos! 💯 💪🏾
What are you trying to fix?
wow much better vid than MAYO3LT
I suspect cleaning it on the engine leads to Clogged Cat.
Had to replace one of those (only $600).
Ya'll make it look simple It's 10° outside right now so if I put some shit in the tank like Seafoam will that help? I can feel the rough idle in the steering wheel and it has a slight miss at idle when sitting at a light with it in drive
It might help. Depends on what the problem is. But it definitely cant hurt to run some fuel treatment or injector cleaner for sure.
Thx Bud!
I watch the both of your videos on how to change the fuel filter and the plugs I've got a 2002 Envoy and I wanted to know how big the gas line is from the fuel tank to the fuel injection because I've got one on my car that looks like a water hose but it's black plastic can you please respond as soon as possible when you see this video I'm A desperate woman mechanic shade tree mechanic
There is 3 lines. The supply line is 3/8" and the return line is 5/16" and the evap line is also 5/16"
Heres a link that shows diagram. content://com.android.chrome.FileProvider/images/screenshot/16375169741898595655901374270891.jpg
Hello! I am from Russia and I also have Envoy 2003. After cleaning the throttle does it need to be adapted again or does it adapt itself? I want to clean it, but I'm afraid that then the engine will be unstable.
If you unhook the battery cable for 30 minutes it will reset the throttle position and the ecm (engine control module)will adjust it to the correct position
@@GrimeTimeWithKenny Thank you so much! I did not know it. Now I'll clean it calmly ) In Russia, this is a very rare car. Many Trailbalzer collected them in Russia under license. But, it is still difficult to find information on self-repair.
@@GrimeTimeWithKenny you can look at my Envoy on my channel, only there in Russian)I also tell you how to repair it, there is no need to understand the language
I heard it's bad to turn the disc cause it messes with the position? If I do this should I disconnect the battery, wait 30 minutes, then clean it, or clean then re attach and disconnect 30 minutes?
I just disconnected the battery while I cleaned mine which was 30 minutes or longer
@@GrimeTimeWithKenny what about turning the disc though? Did doing that cause issues? I've seen people saying it does and I'm cleaning mine this weekend so I wanna be sure
It wont cause any problems
Mine is stalling at idle, but that's only when the AC is on, I researched it, and a lot of the results had to do with the throttle body being dirty. I'm gonna take mine off my 'Voy tonight. 👍🤜🤛
Worth trying Sure cant hurt it
Hey, I'm having the same issue with my 05 Trailblazer. A lot of my research leads me to this being the fix for the most part. Did you end up cleaning the throttle body and did it fix the stalling for when the A/C was turned on?
@@MasterPeaches It definitely helped the stalling issue, however my truck a couple of times after I've cleaned the throttle body, would stumble a little bit, but won't stall.
@@2010MegaScooter Noted, thanks! Would your Envoy ever stall so bad when the A/C was on to a point it would turn the car off? Just like in this video.
@@MasterPeaches Before, yes. After my truck has stumbled a couple of times, but never stalled. Yet. My RPM needle would drop to 400-300 and my truck recovers. My catalytic converter might be a culprit too. I was told it might be blocked partially.
That was cool! I'm learning to be my own mechanic. What reasoning is there to tear out council. U can reach on passenger side with your whole hand. That's not rite
I think someone 🤔 is destroying my car little by little. Now it's stranded side of road. I think ran out of gas. They messed with instrument panel so i hope it it just ran out. Whats easiest way to smart.
I cleaned mine and about 48 hours later the dam thing started making a loud buzzing noise every time you tur. The ignition on.
It's 20 below wind chill and i gotta clean mine without a garage to do it in... any tips😂
Say screw it lol
Yeap, I'm just going to replace it. 👍
What's the band in your music for video
It's in the description
Why do you need to unhook the battery?
To reset the computer so it will learn the new throttle position.
You don't have unbolt the throttle body just use a can of amsoil power foam
Hey bro
Would throw valve body cause it just to shut off and crank right back
Would the valve body cause the engine to shut off ,I just crank it back up in neutral crank ,while it is rolling ,very dangerous
Did it make a difference is it running better?
Yes got rid of the hesitation when at idle and during acceleration.
For everyone that will see this, carbon is a real issue!
It wouldn't have been a bore to test drive before to show people what issues you were having and then test drive again afterwards to see if it actually did make a difference and to let others see. JMHO
Yea I should have. I've got a few comments about that. Just didnt think of it at the time
Ok 👍 good job I just got a 2005 gmc envoy had the 2003 envoy and the engine went so I am ripping parts off the 03 to use for the 05 great idea on pulling the hole plate from the part I will be doing that take my word these truck are the best on the market even after my engine went on the 03 that was my fault will never happen again
this has got to be the biggest waste of time I've ever seen on this particular job. don't remove it. get a damn tooth brush, spray your chosen solvent and scrub the intake. it's just air.
Clearly has no schooling or education in auto repair, doesn't even know the names of the parts, hahaha 😢😮
Great video
