Very low rough idle. Car starts a little hard. Will stall if not giving pressing on pedal. New O2sensor' s. Doesn't overheat. Doesn't burn oil. Do notice exhaust smell. Exhaust louder than normal. Will blog sometimes on acceleration. New fuel pump, filter. Maf sensor six months old. Idle Air Control about a year old. Cleaned both. When IAC electric plug removed idle climbed to 1500 rpm but it did not run rough or stall. Code 171, lean. Any suggestions would be appreciated.
