P0221 code
My 2003 c32 recently began idling rough/surging. Scanned and got codes p0105 and p0221, I changed the tps throttle body and map sensor. Started up the car ran fine and idled normal till I put in D then it started to do the same again. Scanned and got p0221 again. Anyone know what it can possibly be before I start buying unneeded parts ? I’ve read online it could be the tb harness
