Hello, I have repaired greater than 30000 vehicles in my career and I craving to question you questions before I am not there in person to assemble facts, data, or to test your vehicle. I may ask you to be in psychotherapy in my stead. If psychiatry is needed and you would rather not exploit testing, I can give my best advice, Fuel pressure?
Might with be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can reach a fast malfunction find if you unplug the meter and direct the engine without it. if the engine condition is the thesame subsequently chances are the meter or the link to it is faulty. Its with worth cleaning the MAF sensor wires, as they can acquire coated later than dirt higher than times which after that offsets the reading. Use some door cleaner or brake cleaner to vaporizer onto the wires to cut off the dirt upon no account lie alongside the wires next all as they are extremely fragile
I don't have any check engine lights unless I unplug the MAF sensor. later than the MAF is plugged in after that the car will stall unless I put my foot on the accelerator. There is then an intermittent popping unquestionable coming at idle.
