This could be an airleak after the airflow meter, any freshen dragged in here isn t seen by the ECU and suitably not compensated for and can thin the engine out and can after that permit the engine to rev in the works following not desired causing brusque running. As its a mechanical anomaly it tends not to approach on the oddity open and you can sometimes hear a hissing noise with the engine running.
Might also be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can accomplish a quick fault locate if you unplug the meter and control the engine without it. if the engine condition is the thesame next chances are the meter or the relationship to it is faulty. Its in addition to worth cleaning the MAF sensor wires, as they can get coated similar to dirt exceeding epoch which later offsets the reading. Use some gate cleaner or brake cleaner to spray can onto the wires to cut off the dirt upon no account be adjacent to the wires in the manner of whatever as they are utterly fragile
I don't have any check engine lights unless I unplug the MAF sensor. subsequently the MAF is plugged in after that the car will stall unless I put my foot upon the accelerator. There is next an intermittent popping sealed coming at idle.
