Genuine Parts 12679524 Fuel Injection Throttle Body with Throttle Actuator

I purchased this for a 2008 Hummer H3 Alpha (5.3L). It fit perfectly. It works perfectly. The ONLY thing to keep in mind is it does not come with the little round gasket that goes behind it. My gasket was ok, yours may not be. It'll save you a trip to the store to have one on hand.**Edit** I forgot to add, there is a programming/relearn procedure. There's a gm guide for it, it's only a few steps. I left a screenshot of the guide I used. It worked on this gm brand, hopefully it works for you.1. With vehicle in park, crank vehicle and let it idle 3 minutes.2. Turn off vehicle for 1 minute.3. Repeat step 1.4. That should be it. There's additional steps if the relearn fails for you, but mine went flawlessly.

Very easy job. Dealer quoted us over $700 for this job on our 08 suburban that was having catastrophic failure of the throttle body. Reduced power, and eventually the throttle was completely unresponsive. It would idle and never rev.Literally under 10 minutes and we had it installed and all plastics put back together. We put a new AC Delco gasket in also which was a totally unneeded waste. Old gasket was fine after 175k miles.Here’s the tough part... I’ve done this job twice on late model Chevys. The idle relearn procedure is a real pain without a scan tool. Never as easy as YouTube says... It has taken several days of driving and idling to get the idle to drop back down on both vehicles. Make sure you remove your negative battery cable and hold it on your positive terminal for a couple minutes throughout the relearn procedure. It still doesn’t fix it right away but it helps a lot! Eventually the idle will drop back down but it is just simply a pain.Also, don’t do what I did and wait for the first snow of the year to do the job. Driving “in excess of 44mph with multiple acceleration and deceleration cycles” as you’re supposed to in several inches of snow, at night, with an idle stuck at 3,000 rpms, active ABS, and an empty gas tank, was not my best decision...The upshot... the actual repair is stupid simple, Amazon is far cheaper than dealer parts (duh), and expect the relearn to be a pain but doable for the average Joe.Also, if you have high miles, expect to break your PCV hose on this job and order a replacement before you try. Or use 3/8” radiator hose in a pinch like me. (1/2” would be better...)

I usually just do an annual cleaning of my throttle body, but I opted to replace the throttle body this year. What an improvement. It was a plus that I had zero problems, and instalation was a breeze.

It's possible you will need the tools and know how to reprogram your vehicles computer or you will need to take it to your local dealer. You may experience idle issues until this is done. If not not you got lucky like me. Don't touch the butterfly while installing the throttle body. In my experience, I had slightly high idle 800rpm for about 2 weeks until the computer was able to adjust to the new throttle body. Runs like a champ know and idles between 500 to 600rpm. If you experience a higher rpm at idle I would recommend hooking up the computer and reprogramming it. Great factory part!

Our 2007 suburban had a castrophic throttle body failure. Reduced engine speed and basically put it in limp mode. We bought this part and changed it out. Truck ran like a brand new one for about 2 weeks no issues at all then bam all the sudden check engine like for throttle body with reduced engine power and limp mode again. Husband is a mechanic thankfully and going to hook the scanner into it and try to relearn it. Hoping this works. We will take spending $145 for a OEM part anyway when dealer wanted over $500 just for the part alone. Great buy as long as we can get the computer to relearn the new throttle body.

This is for a 2007 5.3 liter Chevy engine.

Fit perfectly and very durable. Been in my truck for over a year with no issue

Like I said the part was as good as it can get BUT I ordered the wrong part. The shipping was very fast and if I need another part I would have no problem useing this shop again
