    I've been watching all sorts of videos on TH-cam 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 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!

    • @backyardchevy328
      @backyardchevy328  2 ปีที่แล้ว +1

      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?

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 ?

  • @cableguy130
    @cableguy130 ปีที่แล้ว

    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!

    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.
