This is crazy, twice now you've put out the exact repair I have to do on my colorado less than a week prior to me having to do it. Been repairing cars my whole life but your videos are just perfect as a case-specific reference and I really appreciate the quality of both filming and explanations.
Easily one of the best youtube mechanics.
Thats awesome🙂 so glad to be able to help and i really appreciate ur comment it means a lot..thank you
I've been watching all sorts of videos on CZcams regarding this procedure. Although they showed how to do the procedure but we're lacking on some of the information. You sir by far did the best job at explaining this complete procedure, including on how to reset the idle for a Chevy/GMC. Thank You.
Thank you🙂 i really appreciate the comment, makes me feel much better about my videos🙂
Great video! These first gen Colorados are good, easy to work on little trucks.
great video. done this to my '05 awhile back and it worked wonders
Thank you🙂 yea on this one the idles so much better too
Hey boss thanks for hammering out all these videos. I have had to clean my throttle body twice a year for the last three years. I went from high milage commute to a 7 minute drive a year ago. Is this frequency normal? Chevy cobalt 2010
Yea high mileage commutes cause a lot of blowby and carbon deposits which settle on the throttle body hitting the throttle body blade..and if its a higher mileage vehicle with a bad or clogged pcv valve even moreso due to the excess crankcase pressure.
@@backyardchevy328 is the pcv valve under the manifold? I dont see it
@@joeschatz6617 its part of the valve cover..it has that hose under the air resonator connects to the clean side of pcv..while the intake connects to the dirty side of pcv valve
@@backyardchevy328 yes thank you so much! I see it is difficult to find a new valve cover. Lots of used ones for sale, but then one wonders if the pcv valve is good or bad.
@@joeschatz6617 The PCV orificed tube restricts the flow rate of the blow-by gases using a 2.5 mm (0.098 in) orifice located in the camshaft cover tube. If abnormal operating conditions arise, the system is designed to allow excessive amounts of blow-by gases to back flow through the crankcase ventilation fresh air tube into the air cleaner resonator in order to be consumed by normal combustion.
Hey backyard Chevy, it's good to see you do some work on that Colorado, I have a 2006 with a 2.8 I noticed your engine seems to be different than the one I have, because I don't have that small vacuum line on the side of my resonator. I work on my Colorado watching your videos, also sent you an email sometime back. I did this job on my Colorado but I did it with the throttle body on, cleaned it real good because it was running kind of rough also cleaned MAF sensor. But I didn't do the last step with the idle, just started it up let it run for a few minutes turned it off, and then took it for a ride she is running great. I have a question have you ever changed the transmission fluid on that vehicle or do you recommend it? I have 112500 miles on it, I bought it use with 105000. I hear that you shouldn't because it will mess up the transmission by putting new fluid. What is your take on this? Thanks for the video keep them coming it helps me out alot.
Thank you🙂 i changed it when we got it at about 75k miles..what i do is smell the fluid if it looks brown and burnt i dont change the fluid..cause any burnt smell will definitely have worn out clutches..and if u change the fluid it may cause em to slip cause the fluid loses that gritty texture...but at that mileage if u feel and it looks like it hasnt been changed it may be risky.
I followed your video, and what a difference on my 2004 Colorado. Thanks for posting. Great job and was easy to understand.
Isn’t it bad to open the butterfly valve by hand ? It’s electronically activated…
Dude! I just bought my 08” canyon and I can’t get that grey/ white clip to push down to release on that line… any ideas ?? It moved fully up but I can’t push it down???
Rare win for CZcams these days when you find simple tutorial teaching exactly what you need. Thank you, Backyard Chevy.
Best videos on the internet! Question: Is the idle reset procedure after throttle body installation the same for a 2017 Colorado? Do I have to disconnect battery to begin replacement?
I have an 07 Hummer. I assume it is the exact same. Loved the video. What a great service you are doing!
Love you man
My 2010 colorado was idling really rough. Followed your video, fixed it in about 30min. Idles much smoother now. Great video.
Your video helped me bring my 2005 Colorado back to it’s beautiful normal idle. Thanks for making an awesome video man, very well done. New life long subscriber here.
We’ll it’s been covered how good of a video this is, but thank you! 06 stalling at slow down, fixed! My new go to channel
Great video thank tou
good job
This is the second time you have rescued me, last time on my brakes, very good video thank you for helping out😃😃
Great video, thank you. The carbon build up blocks the air around the throttle body used for idle. The ecu then has to open the throttle to prevent stalling which causes some surging before it settles out. For colarado simply clean around the throttle blade opening. Other vehicles might have idle air ports or holes in the throttle plate or even a seperate idle air control valve. My truck didnt look bad at first sight but sure enough it was the issue, Thank you!
Can I use a paper towel instead of a brush? If not, will an old toothbrush work?
Who is this idiot!?
i was told you are not supposed to open the flap on an electronic throttle body. this may cause problems. is it ok to open the flap for better cleaning access with the throttle body off the engine ? i have a 2009 chrysler town and country with the 3.8 V6 engine.
Hi, how to call that clip on the plastic hose? The white one the one you need to push to pull hose of trottle body, I accidentally broke and need to replace it but struggle to find it, please help
Oh yeah, thank you for sharing this video. I especially like the fact that you included close ups and tricks for releasing the clips. I broke mine the 1st time I cleaned my Throttle Body.
Do these trucks have 'G. D. I. (Gasoline Direct Injection)?
While I have the Resonator off, can I run cleaner through it as well?
I tried this today and got as far as the hose with the white clip, but pressing down on the white part didn't release it ....does that mean it's broken and needs a new clip ?
The white clip an be triky jest press down on both sides and wiggle with pressure
Followed your video and immediately had improvements to my vehicle. Shortly after I had a P0017 to replace my camshaft sensor, and after doing so engine has improved. However, my newest problem is that if I get a low idle while driving my 2006 Chevy Colorado 2.8 L stalls and the check engine light comes on. Taking it to a mechanic soon but do you have any idea what could be causing it?
What did you find out from your mechanic?
A thin layer of Vaseline we'll make the gasket the gasket moist And it helps to make a good seal
I have a 2011 2.9L. I followed your instructions and the throttle body was very dirty. Got it nice an clean, but still a low idle. It sits between 600-700 rpm. Could there be another issue? Nice video...thank you.
Is it the same procedure on a standard and an automatic ? I have a 5 speed standard with the same issues low idle and turns off.
Yes, itll be the same procedure
Thank you so much for your help, great video 👍
Thank you🙂
Great tutorial, clear and easy to understand. The video work is outstanding. If you do the clean without removing it or disconnecting the wiring will the relearn be needed?
No, unless it was so dirty that it changed the amount of airflow its receiving at idle
Just bought an 07 Canyon. Your channel is amazing. Thank you for all the beautifully detailed videos. God bless you man.
Thank you🙂 i really appreciate it
Cool
Thank you🙂
Can replacing the air filter and cleaning the MAF sensor also help fix the code
Yes, the idle code can also be affected by a dirty air cleaner or maf sensor not reading airflow
I have some left over carburetor cleaner. Can I use that?
Yes, it can be used...only difference is throttle body cleaner is better at penetrating and breaking down carbon deposits
@@backyardchevy328 I used carb cleaner, because I had some. I'll check it again and use the throttle body cleaner. Thank you.
I took off the throttle body and unscrewed the blade and put everything back together exactly like it was but I forgot that small vacuum line and started it and it ran even worse then I put the vacuum line back on and let it idle for like a minute and shut it off
Yea that would cause it to run bad
Sub'd !!!! Got an 05 crew cab that seems to have ABS issues i think. brakes seem to stick or hang at times causing a strain on the truck, when i put it on jack stands all tires turn freely '
Normally abs issues would be brakes locking up or brake pedal taking more effort to stop, or the abs light would come on..Any abnormal brake wear or brakes getting hotter than normal?
I am going to try this on my
2004 chevy colorado. I'm hoping this solves my low idle issue. Thanks!!
Hopefully it does🙂 good luck
My throttle body was really dirty, I cleaned it out and it didn’t fix the issue for me. Now my question is do I need a new throttle or is that not the issue with my 05 Chevy Colorado. It’s been saying traction fault
If ur getting a traction fault error its normally related to the wheel hub/wheel speed sensor malfunction..have u had it scanned?
I’ve been trying for like a day to unplug the cord into the throttle body fucking my hand up everytime I do it
The hose attached to the side with the white clip? That one just push in on the white clip and that causes tabs to open up on the sides allowing it to slide out
What is the box that the throttle body attaches to?
Well it bolts up to the intake manifold...but the box that connects to it with the air tube and clamps is the air intake resonator box
Anybody know what the wire cable hooked up to the throttle body actually is? The one with the white clip he punched down to remove
Its a vapor canister purge valve hose i believe
Thank you for the video. Really appreciate you including the relearn process after cleaning the throttle body.
Should the negative batter cable be removed prior to cleaning unit? I’m guessing so seeing as there are electrical connections that need detaching and because you included the relearning process.
Question, is there any situation that you might be doing a vehicle repair in which disconnecting the battery isn’t recommended? Otherwise, I’m just going to assume that doing so, is (at worst) a safety precaution when doing repairs and just make it part of my routine when working on my truck.
Thanks again. Como se llama? Una vez, muchas gracias!
Yes, it would be safer to do with the negative terminal disconnected...well the drawback to disconnecting the battery is it may forget all the learned adjustments so some cars may not want to run so good til it relearns those values..but yes other than that risk its always safer to disconnect the battery before any work that involves anything electrical.
@@backyardchevy328 thank you, and good to know. Hey, I have another question.
I had a person working on my 05 Chevy Colorado a couple years ago and he set my resonator box on fire because he had messed up my pass lock system and was trying to fix it (which we did a workaround for by cutting a white/blue wire behind the steering column). He replaced the resonator box with one that looks similar to the one I had before. However, when starting to remove my throttle body earlier today, I noticed that the resonator box on this one doesn’t have a connection stem for attaching/detaching the hose going to the fuel pressure regulator.
He got the current resonator box from a vehicle at a local pull a part junkyard. So, I’m wondering...is it possible that the one he got one off another Colorado of a different year or some other interchangeable gmc model that doesn’t have this connector stem for FPR hose? Because I’m not sure if my 05 Colorado should even have this stem on the resonator box like you have in this video here, but I’m thinking it did because there is another area close to where I see your hose attaches to the resonator box that I’ve thought something must attach to that but is missing since he replaced the burnt one. And I’m an inexperienced DIY mechanic so, I’m not sure if my old one had a connection spot on it or not. I’m thinking it did because I recall seeing (what looks a lot like ) an FPR valve hose at Autozone Online for my 05 Colorado lying around my shop sometime since this event a couple years ago.
It just makes me feel like he may have just removed this hose entirely since he didn’t have a stem connection to attach it to on this replacement resonator box.
Any thoughts or insights on this?
@@CZcamsStudio101 for the fuel pressure regulator? What does it have on the fuel pressure regulator right now? A plug or is it routed to some other vaccum port?
@@backyardchevy328 there isn’t a hose coming off the top of the fuel pressure regulator. So, I’m guessing there should be something, yes? I’m not sure what it’s supposed to look like (assuming FPR can vary).
@@CZcamsStudio101 czcams.com/video/yJi1ZNYF3Yc/video.html at 5:29 i show the fuel pressure regulator for the Colorado..if it has a port on top without a hose connected to it..then you will need go get that fixed..if not fuel pressure will be too high and could cause a variety of issues
Awesome video, very helpful. Thank You.
Thank you🙂
Well done. Thanks for including idle relearn procedure.
Thank you🙂
Awesome. Thanks a lot. I fixed my 2011, 2.9L Colorado truck this morning by doing exactly this! I don't have a vacuum line on the front like this one, but everything else was spot on! My truck would try to go dead when I was coasting into a parking spot, or backing into one. Mine was dirtier than yours, but a 5 dollar bottle of throttle body cleaner from advanced auto parts, this video, an hour of time....perfect again. You saved me about 300-400 bucks!
Thats awesome! Great job🙂👍
@@backyardchevy328 Also, I forgot to mention that mine had the "check engine" light that would come and go. After cleaning, I did your 3 minute idle, 1 minute off. 3 minute idle on again, 1 minute off. This took care of the light like you said it would. The young guy at advanced auto parts checked my computer. He tried to tell me I needed some kind of electronic piece, or that I may have a burned wire. I told him "just sell me this 5 dollar can of throttle body cleaner, and I'll come back if need be, lol." No need to go back. Thanks again!
@@jjbar8285 lol, why would he tell u such a thing...glad u were able to get all that fixed🙂👍
@@backyardchevy328 Lol. I don't know. He was very young. He looked up the code on his cell phone, and he said it looked like an expensive electronic part might be bad. He didn't know what he was looking at. Just trying to make commission on a sell I think.
Thanks so much for your video
Anytime🙂 thank you for the support
Thank you so much for this video bro. You are so well spoken and easy to follow! My brother and I were able to get my 07 Colorado back running again because of this video!😎
Thats awesome!👍 thank you🙂
I've had my 2007 colorado for 7 years now and it's approaching 200k miles. It's having some issues, and I'm not really a mechanic, but your videos have helped me fix it up and get it to running back like when I first got it, or possibly better.
That's awesome!🙂👍 im so glad to be able to help
I have p0171, someone suggested I do this. I have a bumby idle sometimes.
Yea for a lean code youll wanna check anything that can affect air flow like a dirty air filter..a dirty maf(i did a video last week)..a vacuum leak like air tube or intake..a sticky throttle body could cause it...dirty injectors..or a bad(dirty) oxygen sensor..i would also start with checking or cleaning the maf sensor since its the easier one to clean(check)
@@backyardchevy328 noted, I'm waiting on this rain to quit then I'm gonna start trying to get rid of this dang code. thanks for the response!
@@ashtons7523 good luck i hope ur able to get it resolved
Thank you for the info brother
Did this on my Colorado and it worked wonders and got some gas mileage back
Thats awesome🙂👍 so glad to hear it
I have a question my dad replaced my throttle body recently and it still been doing the same thing it was before he replaced it. My rpm would shoot up to like 4 or 5 and then die back down then eventually if I turned on my defrost it would shoot up really high then turn my car off. And when I’m driving it almost like it would speed up without me pressing on the gas. Any idea on what I need to do to get that fixed ?
Any codes that pop up? Did u disconnect the battery for over 15 mins and perform a idle relearn? If no codes are present and u did perform a relearn..id look for a vacuum leak like a torn or disconnected vacuum line..or possible bad intake gasket..or even a dirty maf sensor
Awesome! Thank you
Thank you🙂
