This could be an airleak after the airflow meter, any expose dragged in here isn t seen by the ECU and so not compensated for and can thin the engine out and can also permit the engine to rev stirring in the same way as not desired causing harsh running. As its a mechanical malformation it tends not to perspective upon the idiosyncrasy roomy and you can sometimes hear a hissing noise later the engine running.
I did re-check them tho. The master tech did extensive tests upon the freshen flow meter and said it was good. following I unplug it and control the motor, the car runs sharp and at 850ish. I can deserted guess that my additional 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 rule in the swap of rpm though? I think it unaided adjusts it nearly 1k..
