Hello, I have repaired exceeding 30000 vehicles in my career and I infatuation to ask you questions since I am not there in person to accumulate facts, data, or to test your vehicle. I may ask you to play a role chemical analysis in my stead. If breakdown is needed and you would rather not undertaking testing, I can manage to pay for my best advice, Fuel pressure?
I did re-check them tho. The master tech did extensive tests on the freshen flow meter and said it was good. as soon as I unplug it and rule the motor, the car runs rude and at 850ish. I can without help guess that my further rebuilt ecu has an issue, or the tps needs to be re-adjusted, or someway my maf has died in the midst of all this. I don't think the tps has that much manage in the vary of rpm though? I think it lonely adjusts it with reference to 1k..
