This could be an airleak after the airflow meter, any air dragged in here isn t seen by the ECU and therefore not compensated for and can lean the engine out and can as a consequence allow the engine to rev going on afterward not desired causing harsh running. As its a mechanical aberration it tends not to outlook upon the irregularity open and you can sometimes hear a hissing noise once the engine running.
I did re-check them tho. The master tech did extensive tests upon the expose flow meter and said it was good. next I unplug it and control the motor, the car runs brusque and at 850ish. I can unaccompanied guess that my new rebuilt ecu has an issue, or the tps needs to be re-adjusted, or anyhow my maf has died in the midst of every this. I don't think the tps has that much control in the swap of rpm though? I think it unaided adjusts it all but 1k..
I'm reviewing your ask now, and will read out urge on behind your reply ASAP. Rgds Greg. What irregularity codes realize you have. Does the engine run subsequently the MAF disconnected. afterward the loud hissing unquestionable this could be your problem. This could be a large vacuum leak ,with the MAF amalgamated it is by yourself measuring the ventilate that is getting following the MAF, thus if the intake manifold is sucking in air the ventilate to fuel ratio will be definitely out and cause the engine to stal
