I'm Awesome
i have a vortec v6... OBD2 everything your saying my truck does the same.. ive had mine on a scanner GM tech2 and mine showed it miss firing and the IAC was moving slow... so i pulled the TB off cleaned it with GM top eng. cleaner or X66 then replaced the IAC, TPS.. this didnt change a thing!!! i was watching the O2's and one bank was running lean (NO check eng light) and that made me look at the intake so i shot a lil brake cleaner in the motor.... it res up!!
also just FYI if you keep driving it, it will knock your cat out... it did on mine
