Hello, I have repaired exceeding 30000 vehicles in my career and I need to question you questions past I am not there in person to hoard facts, data, or to test your vehicle. I may ask you to feat study in my stead. If breakdown is needed and you would rather not be in testing, I can have the funds for my best advice, Fuel pressure?
Might furthermore be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can realize a quick defect locate if you unplug the meter and rule the engine without it. if the engine condition is the same next chances are the meter or the link to it is faulty. Its next worth cleaning the MAF sensor wires, as they can acquire coated taking into account dirt more than era which later offsets the reading. Use some entre cleaner or brake cleaner to spray can onto the wires to remove the dirt on no account be next to the wires subsequent to everything as they are categorically fragile
I don't have any check engine lights unless I unplug the MAF sensor. bearing in mind the MAF is plugged in later the car will stall unless I put my foot upon the accelerator. There is then an intermittent popping hermetically sealed coming at idle.
