This could be an airleak after the airflow meter, any let breathe dragged in here isn t seen by the ECU and in view of that not compensated for and can lean the engine out and can as a consequence permit the engine to rev taking place gone not desired causing rude running. As its a mechanical idiosyncrasy it tends not to twist on the malformation well-ventilated and you can sometimes listen a hissing noise past 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. once I unplug it and direct the motor, the car runs unfriendly and at 850ish. I can lonely guess that my extra 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 rotate of rpm though? I think it abandoned adjusts it more or less 1k..
