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 thin the engine out and can also permit the engine to rev occurring similar to not desired causing sharp running. As its a mechanical idiosyncrasy it tends not to outlook upon the malfunction lighthearted and you can sometimes hear a hissing noise later than the engine running.
Might moreover be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can realize a fast deformity locate if you unplug the meter and govern the engine without it. if the engine condition is the same after that chances are the meter or the membership to it is faulty. Its after that worth cleaning the MAF sensor wires, as they can get coated similar to dirt on top of become old which subsequently offsets the reading. Use some gain access to cleaner or brake cleaner to vaporizer onto the wires to surgically remove the dirt on no account adjoin the wires subsequently anything as they are unquestionably fragile
I don't have any check engine lights unless I unplug the MAF sensor. like the MAF is plugged in after that the car will stall unless I put my foot upon the accelerator. There is moreover an intermittent popping unquestionable coming at idle.
