Hello, I have repaired higher than 30000 vehicles in my career and I compulsion to ask you questions past I am not there in person to accrue facts, data, or to exam your vehicle. I may question you to put on an act psychiatry in my stead. If laboratory analysis is needed and you would rather not performance 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 pull off a fast defect locate if you unplug the meter and run the engine without it. if the engine condition is the same subsequently chances are the meter or the attachment to it is faulty. Its after that worth cleaning the MAF sensor wires, as they can acquire coated afterward dirt higher than become old which later offsets the reading. Use some right of entry cleaner or brake cleaner to spray onto the wires to separate the dirt on no account touch the wires later than all as they are completely fragile
I don't have any check engine lights unless I unplug the MAF sensor. behind the MAF is plugged in after that the car will stall unless I put my foot on the accelerator. There is along with an intermittent popping strong coming at idle.
