My wifes 2003 yukon xl has P0220 coming up and has a rough idle. I purchased a TPS(throttle Position Sensor), but her model doesn't have one. I believe it is built into a big plastic piece on side of throttle body. It looks as though I need to replace entire throttle body. Do I need to go with AC Delco? Is there a performance upgrade that's worth purchasing? Thanks!

That "big plastic piece" is the TPS. Is the yukon drive by wire (DBW)? Does the big "plastic piece" have a wiring harness plugging into it with around 8 wires or so? If so then its DBW. The TPS is riveted to the throttle body (4 of them). Drill them out and the replacement TPS comes with nuts/bolts. Easy to change but typically requires a idle relearn. Easy enough. Google the procedure.
Here is the replacement of a TPS sensor with cabled throttle.
Here is the replacement of a TPS sensor with DBW. You dont have to remove the throttle body unless you wish to give a thorough cleaning.
