Car Running way rich at idle at idle when i start the car it sounds fine. then it gradually starts getting a ruff idle. The STFT and LTFT start to go up and after a while the LTFT on the driver side maxes out. pass side not as bad. but still high.
the o2's sit really low around 175 to 300 mlvs so it just keeps adding fuel. if you give it throttle they will move between 200 and 900. and the STFT and LTFT will go back to zero.
pulled and changed the plugs driver side were really black and passenger side looked fine.
have replaced the o2's about 3 weeks ago
