What's up guys.. I just bought a used 04 G35 6mt and fell in love with it during the rest drive.. There is so much potential behind this engine and it's a beautiful car in and out.. I've already dealt with the p0011 and p0021 rat away as an SES light came on a day after I bought, thank God I bought a warranty.. Car has 141000 miles.. Every part that has to do with those codes was replaced with new parts and I mean every part involved.. 2500 dollar repair, they let me test drive it and it was so much slower and hesitates so much compared to when I first had it for those 2 days before taking it back in.. Now they're replacing the engine control wiring harness because they found a bad ground in the system from solenoid bank 1 sensor to the ECU.. Could that really.make my car drive that bad?? I feel like that dealership broke my damn G.. Input, anything or anyone have similar experience??
