Hello, I have repaired higher than 30000 vehicles in my career and I need to ask you questions in the past I am not there in person to stockpile facts, data, or to exam your vehicle. I may ask you to do its stuff psychotherapy in my stead. If breakdown is needed and you would rather not be active testing, I can pay for 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 accomplish a fast defect find if you unplug the meter and run the engine without it. if the engine condition is the same next chances are the meter or the connection to it is faulty. Its also worth cleaning the MAF sensor wires, as they can get coated behind dirt more than become old which after that offsets the reading. Use some way in cleaner or brake cleaner to vaporizer onto the wires to separate the dirt on no account be next to the wires in imitation of whatever as they are utterly fragile
I don't have any check engine lights unless I unplug the MAF sensor. like the MAF is plugged in later the car will stall unless I put my foot on the accelerator. There is in addition to an intermittent popping hermetic coming at idle.
