Hello, I have repaired exceeding 30000 vehicles in my career and I habit to ask you questions previously I am not there in person to pile up facts, data, or to exam your vehicle. I may question you to take action testing in my stead. If chemical analysis is needed and you would rather not piece of legislation testing, I can give 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 accomplish a quick malfunction find if you unplug the meter and rule the engine without it. if the engine condition is the similar after that chances are the meter or the connection to it is faulty. Its along with worth cleaning the MAF sensor wires, as they can get coated later than dirt more than grow old which then offsets the reading. Use some admittance cleaner or brake cleaner to spray onto the wires to remove the dirt on no account be adjacent to the wires in imitation of anything as they are unconditionally fragile
This could be a large vacuum leak ,with the MAF linked it is unaided measuring the air that is getting in the manner of the MAF, thus if the intake manifold is sucking in ventilate the ventilate to fuel ratio will be enormously out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. past carb cleaner spray vaporizer in the place of the hissing in the manner of the engine government and behind you hear the engine stall or rev future there is the leak ,could be a bad vacuum hose bad gasket upon the manifold.
