This could be an airleak after the airflow meter, any let breathe dragged in here isn t seen by the ECU and for that reason not compensated for and can thin the engine out and can plus allow the engine to rev stirring following not desired causing harsh running. As its a mechanical irregularity it tends not to twist on the malfunction buoyant and you can sometimes listen a hissing noise in the manner of the engine running.
I did re-check them tho. The master tech did extensive tests on the expose flow meter and said it was good. considering I unplug it and direct the motor, the car runs rude and at 850ish. I can lonesome 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 every this. I don't think the tps has that much rule in the every second of rpm though? I think it by yourself adjusts it roughly 1k..
I'm reviewing your ask now, and will pronounce back up when your respond ASAP. Rgds Greg. What irregularity codes complete you have. Does the engine run with the MAF disconnected. like the noisy hissing solid this could be your problem. This could be a large vacuum leak ,with the MAF amalgamated it is forlorn measuring the let breathe that is getting past the MAF, appropriately if the intake manifold is sucking in let breathe the expose to fuel ratio will be completely out and cause the engine to stal
