My Long Term fuel trim is running 139 on bank 1 and 145 on bank 2. The O2's are new Delphi. New Delphi MAF sensor. New FMS 30# injectors. No vacuum leaks that I can find or exhaust leaks that I can hear. The car is running really good and the only thing I can complain about is the idle quality. The MAF sensor helped that a lot and with throttle response as well. Short term fuel trim is spot on at 128 on both sides. Ideas?
