Throttle body acting up

[D is for DENALI]

Well after going thru my receipts I found that it was not a ac Delco part, it was a dorman part... it was one of my only purchases to this truck that was not oe replacement...

This part is for an 03 yukon xl denali 6.0

Here is what I got...

Drilled out the rivets on the throttle body, installed new tps with bolt ons, rewired the pigtail, clasped them together and heatshrunk the sleeves to tighten the moisture barrier, sanded the grounds on the motor, battery terminal, firewall, and voila, my check engine light eventually went away after a few drive cycles and never came back on, along with my reduced engine power limp mode never happened again...

Obviously disconnect your battery first...lol

I would also like to add that while doing this work, it's a great time to get that tb and Maf cleaner out and use some of it.. a fuel/air detailing, of a sort.. air clean and scrub out the filter( or clean,dry, and reoil) make sure its all dialed when it gos back in..

New battery terminal bolts never hurt anyone either...

That price is sensor and pigtail? Not bad. I did the pigtail, which looks exactly like the one in the pic, and eventually I did the complete throttle body. I still get the reduced power, but if I mess with the plug it goes away.

How much was the pigtail? Gm wanted $168 Just for that. I bought an aftermarket. But I'm still having issues. Have a link?

Does it look like this? Amazon has it for under $78 it’s on EBay for $80ish https://www.amazon.com/ACDelco-PT2628-Original-Equipment-Multi-Purpose/dp/B0055AMANA

Mine looks exactly like that one, white wires and all, but way cheaper. As a matter of fact, the one from GM uses all white wires too. The one I bought uses aluminum wire. I'm not sure what GM uses.
