This stared about 2 days ago and Im not sure what the hell this car is doing to me now. The car is a 2002 Camaro 3.8 5spd The codes that are "active" are:

P0172
P1515
P1516
P1120
P1220

Not sure what the "history" codes are since AutoZone cant read history.

I was told that the last 4 are "dealer codes" and that I would have to take these codes or the car to the Chevy dealership to have them figure out what is wrong. The car runs like its on 3-5 cylinders when the reduced engine power light is on and if you shut the car off for about half a minute, then start it, its fine and drives like normal for a few miles, then does the same exact thing! Im about ready to just find some C4 and blow this crap up lol. Any ideas as to whats going on here?

 

P0172 IIRC is left bank rich. Had it on my 96 for quite a while. the other 4 codes all have to do with the TPS. So check that and go from there.
