Hello, I have repaired beyond 30000 vehicles in my career and I habit to ask you questions past I am not there in person to accumulate facts, data, or to test your vehicle. I may ask you to discharge duty examination in my stead. If chemical analysis is needed and you would rather not enactment testing, I can allow my best advice, Fuel pressure?
Might in addition to be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can get a fast deformity find if you unplug the meter and rule the engine without it. if the engine condition is the same subsequently chances are the meter or the attachment to it is faulty. Its also worth cleaning the MAF sensor wires, as they can acquire coated behind dirt higher than period which next offsets the reading. Use some right of entry cleaner or brake cleaner to vaporizer onto the wires to cut off the dirt upon no account adjoin the wires as soon as anything as they are agreed fragile
I don't have any check engine lights unless I unplug the MAF sensor. later the MAF is plugged in later the car will stall unless I put my foot upon the accelerator. There is also an intermittent popping strong coming at idle.
