Hello, I have repaired exceeding 30000 vehicles in my career and I habit to question you questions previously I am not there in person to accrue facts, data, or to test your vehicle. I may question you to action assay in my stead. If examination is needed and you would rather not show testing, I can have the funds for my best advice, Fuel pressure?
Might plus be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can pull off a fast oddity locate if you unplug the meter and govern the engine without it. if the engine condition is the thesame then chances are the meter or the membership to it is faulty. Its also worth cleaning the MAF sensor wires, as they can acquire coated gone dirt greater than period which then offsets the reading. Use some way in cleaner or brake cleaner to spray onto the wires to cut off the dirt upon no account be next to the wires like all as they are unconditionally fragile
I don't have any check engine lights unless I unplug the MAF sensor. in the same way as the MAF is plugged in later the car will stall unless I put my foot upon the accelerator. There is in addition to an intermittent popping solid coming at idle.
