Hello, I have repaired greater than 30000 vehicles in my career and I need to question you questions back I am not there in person to build up facts, data, or to test your vehicle. I may ask you to do something psychiatry in my stead. If investigation is needed and you would rather not con testing, I can pay for 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 accomplish a quick idiosyncrasy find if you unplug the meter and rule the engine without it. if the engine condition is the thesame next chances are the meter or the connection to it is faulty. Its along with worth cleaning the MAF sensor wires, as they can get coated considering dirt higher than time which later offsets the reading. Use some way in cleaner or brake cleaner to spray onto the wires to remove the dirt on no account touch the wires gone whatever as they are categorically fragile
I don't have any check engine lights unless I unplug the MAF sensor. once the MAF is plugged in subsequently the car will stall unless I put my foot on the accelerator. There is then an intermittent popping solid coming at idle.
