This could be an airleak after the airflow meter, any let breathe dragged in here isn t seen by the ECU and therefore not compensated for and can thin the engine out and can afterward permit the engine to rev in the works later not desired causing prickly running. As its a mechanical oddity it tends not to turn on the fault blithe and you can sometimes listen a hissing noise afterward the engine running.
I started the car in the works this morning, it starts happening and runs at 1750 and within a minute or correspondingly climbs exceeding 2500.. It is management mild though, just pretension later than it should be. I as well as checked the throttle screw plate/return screw, purposefully turned it out and nothing changed. put it assist to exactly where it was. No vacuum leak sounds and all associates verified. I air fine about them as I've been in there a bunch of times..
I don't have any check engine lights unless I unplug the MAF sensor. later the MAF is plugged in after that the car will stall unless I put my foot upon the accelerator. There is afterward an intermittent popping sealed coming at idle.
