Hello, I have repaired higher than 30000 vehicles in my career and I habit to question you questions back I am not there in person to gather together facts, data, or to exam your vehicle. I may ask you to enactment examination in my stead. If investigation is needed and you would rather not sham testing, I can meet the expense of my best advice, Fuel pressure?
Might next be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can accomplish a quick malfunction locate if you unplug the meter and run the engine without it. if the engine condition is the thesame later chances are the meter or the attachment to it is faulty. Its then worth cleaning the MAF sensor wires, as they can acquire coated gone dirt higher than era which after that offsets the reading. Use some get into cleaner or brake cleaner to spray can onto the wires to sever the dirt upon no account be next to the wires past everything as they are certainly fragile
