This could be an airleak after the airflow meter, any air dragged in here isn t seen by the ECU and in view of that not compensated for and can thin the engine out and can along with allow the engine to rev occurring behind not desired causing prickly running. As its a mechanical deformity it tends not to viewpoint upon the idiosyncrasy fresh and you can sometimes listen a hissing noise taking into consideration 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. similar to I unplug it and manage the motor, the car runs coarse and at 850ish. I can single-handedly guess that my other 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 control in the different of rpm though? I think it single-handedly adjusts it roughly 1k..
