Hello, I have repaired beyond 30000 vehicles in my career and I habit to question you questions before I am not there in person to accrue facts, data, or to exam your vehicle. I may ask you to perform psychiatry in my stead. If examination is needed and you would rather not put it on testing, I can give my best advice, Fuel pressure?
Might then be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can complete a fast malformation find if you unplug the meter and control the engine without it. if the engine condition is the similar next chances are the meter or the link to it is faulty. Its after that worth cleaning the MAF sensor wires, as they can acquire coated later than dirt beyond period which next offsets the reading. Use some right to use cleaner or brake cleaner to spray onto the wires to separate the dirt upon no account touch the wires taking into consideration all as they are extremely fragile
I don't have any check engine lights unless I unplug the MAF sensor. like the MAF is plugged in subsequently the car will stall unless I put my foot upon the accelerator. There is next an intermittent popping solid coming at idle.
