Hello, I have repaired exceeding 30000 vehicles in my career and I dependence to ask you questions since I am not there in person to collect facts, data, or to test your vehicle. I may ask you to behave psychotherapy in my stead. If examination is needed and you would rather not ham it up testing, I can offer my best advice, Fuel pressure?
I did re-check them tho. The master tech did extensive tests on the air flow meter and said it was good. behind I unplug it and rule the motor, the car runs prickly and at 850ish. I can solitary guess that my further rebuilt ecu has an issue, or the tps needs to be re-adjusted, or anyhow my maf has died in the midst of all this. I don't think the tps has that much rule in the swing of rpm though? I think it solitary adjusts it on the subject of 1k..
