Had the car for about a month and a half now, bought it modded... hasn't had any troubles until now. The engine light just came on, i put an OBDII on it and it said "system running lean" hasn't happened before?? said something about bank 1 or something? i have bigger injectors so i dont see how it would be running lean, i have no way of tuning it either... it has an intense PCM on it but they said they have no records of my vin so i'm guessing it was custom tuned... is there anything else i can use other than hptuners to tune this? or does anyone else have any other suggestions?
