First, I am a retired certified master mechanic of 30 years. Thought I would save a few bucks and went ahead and bought this throttle body by Dorman. I've used Dorman parts over the years and found them to be quality parts, THIS IS NOT. The first unit I put on had bad grinding noise in the gear set and the engine would not even start. I returned the throttle body and they sent another. This one worked somewhat, the motor started but would not idle and went into limp mode after warmup. To late to return so bit the bullet, went to the local store and paid a couple hundred more for a name brand. Installed and happy. Runs Great

It's not the easiest thing in the world to install, but once you get it done, it works well. My vehicle has over 230K miles and it was time. Dorman makes the best product line for after-market vehicle products. Never a doubt about their quality.

This item fixed my issue with throttle body and pedal sensor error codes. Vehicle had check engine and reduced engine power. I replaced the TB harness and throttle body actuator due to age. Cleaned TB and performed relearn. My repair was fixed by replacing TB complete unit. Vehicle has 208k miles and was over due for new TB. I’m not sure why the listing shows not compatible with 03 Yukon XL 1500 Denali 6.0 AWD. But I read on the Dorman website the interchange numbers match will all other branded part numbers. So yes this will work. I also replaced the pedal sensor with the Dorman. I figured I’d get it all done once and for all. I’ve been very happy with Dorman brand products. They have came along way IMO.

I replaced my oem throttle body with this Dorman one, I was having issues with mine during cold morning. It came in quick. I replaced it and so far no issues, very happy with it because the problem seems to be resolved . The price for it is good.

This is exactly what a 298,000-mile Silverado needed. Easy to Install, no issues at startup and within minutes it had recalibrated itself and the truck runs great now. Way to go Dorman.

Bought this to replace my OEM one that had failed and was causing a P1516 code with a reduced engine power message. Decided to take my chance with this Dorman one and it was worse than the original. I did a idle relearn and was constantly getting a P1516 and REP code when the motor was cool. When I reached temp it would work just fine. Problem is you have to keep turning the vehicle off, hook up the scanner and then clear the code. Did a TAC data reading and the projected and actual throttle position was off by over 3%! Bought the AC Delco OEM one and the issue was immediately resolved with a less than 1% difference in projected vs actual throttle position. You can get the OEM AC Delco one here on Amazon for only about $60 more than this.

Good factory replacement. No issues and it does not require a relearn.
