I may ask you to deed psychoanalysis in my stead. If assay is needed and you would rather not accomplish testing, I can provide my best advice, Fuel pressure?
I did re-check them tho. The master tech did extensive tests on the expose flow meter and said it was good. bearing in mind I unplug it and manage the motor, the car runs unfriendly 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 anyhow my maf has died in the midst of all this. I don't think the tps has that much control in the interchange of rpm though? I think it solitary adjusts it as regards 1k..
