Simple change out, pulled info online for the relearn procedure: Heres the throttle body relearn procedure 1) Start the engine and let it idle in park for 3 minutes. During that period the idle may be higher idle than normal. 2) After 3 minutes, turn the engine off and leave it off for 60- seconds. 3) Start the engine again and let it idle in park for 3 minutes one more time. During these run periods you may see a check engine light. Scan for codes and if you get throttle body related codes, clear them. 4) If the idle speed is still off, drive the vehicle at speeds above 44-mph and operate several acceleration and deceleration cycles. Then repeat step #3 one last time. The idle should now be normal My fuel economy has improved from 12-14 mpg to 16.5-18 mpg. Can't beat that! My only complaint, I paid $97.95, and now that I've been prompted to leave a review, the price is $84.95. So I paid $13 more! Good Product Though.

It took me 10 minutes to swap out and fit perfectly. Of course there were other issues with the computer but the throttle body itself is great. Gotta love putting new parts on.

ok straight to the point, so i only had to do the relearn procedure 4 times and those 4 times i started truck 1 min then turn off 1 min, turn on truck 3 min turn off 3min, IMPORTANT do not accelerate or touch pedal while doing first idle checks and when put on drive it will accelerate by it self but just make sure you go from park to drive fast before rpm goes up so it dont kick then turn truck on again and drive for about 10-15min trying to stay on about 44mph as most possible, ALSO once you are ready to shift back to park or reverse or neutral make sure you just hold brake in drive until rpm goes down about 5-10seconds... after 3rd time i notice the change and then 4th fixed in a period of about 1 week. i love how fast 1aauto ship it! definitely will buy more items!

The throttle body I ordered was at my door within 3 days. Not bad for FREE shipping!! The new assembly fit perfectly and was very easy to install. I was able to watch a quick instructional video just to prepare and there was nothing to it. Always pleased with 1a and will always use them for my trucks lifetime!!

I purchased this new throttle body, mainly because it was about the same price as one rebuilt from a parts store. Since it's been installed, my truck is running very well and I've noticed a difference in how the truck runs pulling the ministry trailer. I am very pleased with this part.
What a difference.

What a difference it made replacing the throttle body responsive gets up and goes when u need it. Faulty sensor from the originalt throttle body in my 2007 chevy tahoe. If you are having problems on how the vehicle respond change the throttle body makes a difference.
15 min install - no relearn

I replaced this throttle body on my 2006 Buick Rainier because the Stabilitrack warning kept coming on and the engine would derate. As an added benefit, it fixed a rough shift issue which I thought was a transmission problem. I was going to spend the extra money to get an OEM AC Delco but I have learned to trust 1A Auto when it comes to parts for my Rainier. These guys are really dialed in to the GM 360 platform so I get all my parts here.
Relearn my be required

Ordered this for my 2008 GMC Sierra. Part came quickly and the install was a snap. It cured all my rough idle and hesitation issues but my idle was higher and sometimes the engine would rev up and not come down, like the throttle was sticking. I tried unhooking the battery and every other computer reset I could find on the web, but they either didn't work or only worked for a short time. After my truck stuck at 3000 rpms and put me in a tough situation on the interstate I had to take it to the shop. A 10 minute relearn on my ECM had my truck running perfect. There was nothing wrong with the part, I have nothing bad to say about the part I just wished it came with literature explaining that a relearn may be necessary and to test drive your vechile in short distances before trusting it for the road.
Awesome fixed my problem

I purchased a throttle body for my chevy on 02/23/21 for my chevy. It failed on Memorial Day ,while travelling to the lake for a picnic. Worst auto part purchase that I have ever experienced. Will never make another purchase from this company. Will buy from auto zone from this point on. Pulling the part off the vehicle and shipping it back is to much trouble. Especially if your dealing with cheap low quality parts like this company sells.

Anyone that complains about this throttle body. Must have gotten a factory defect one.. car runs great again after replacing. Also didn't have to program anything. Plug and play. Also seems like I'm using a little less ?
