Hello, I have repaired higher than 30000 vehicles in my career and I need to ask you questions in the past I am not there in person to pile up facts, data, or to test your vehicle. I may question you to feign examination in my stead. If psychoanalysis is needed and you would rather not acquit yourself testing, I can allow 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. similar to I unplug it and direct the motor, the car runs argumentative and at 850ish. I can without help guess that my extra rebuilt ecu has an issue, or the tps needs to be re-adjusted, or somehow my maf has died in the midst of every this. I don't think the tps has that much manage in the every other of rpm though? I think it abandoned adjusts it as regards 1k..
This could be a large vacuum leak ,with the MAF partnered it is deserted measuring the expose that is getting considering the MAF, suitably if the intake manifold is sucking in air the let breathe to fuel ratio will be certainly out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. considering carb cleaner vaporizer spray can in the place of the hissing in imitation of the engine executive and with you listen the engine stall or rev later there is the leak ,could be a bad vacuum hose bad gasket on the manifold.
