Hello, I have repaired higher than 30000 vehicles in my career and I habit to ask you questions since I am not there in person to accrue facts, data, or to exam your vehicle. I may question you to sham scrutiny in my stead. If testing is needed and you would rather not discharge duty testing, I can provide my best advice, Fuel pressure?
Might as a consequence be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can pull off a fast fault locate if you unplug the meter and manage the engine without it. if the engine condition is the thesame then chances are the meter or the association to it is faulty. Its next worth cleaning the MAF sensor wires, as they can acquire coated behind dirt beyond epoch which later offsets the reading. Use some get into cleaner or brake cleaner to vaporizer onto the wires to sever the dirt upon no account adjoin the wires similar to all as they are no question fragile
I don't have any check engine lights unless I unplug the MAF sensor. when the MAF is plugged in then the car will stall unless I put my foot upon the accelerator. There is in addition to an intermittent popping sound coming at idle.
