Now you might think that spraying lighter gas concerning a warm engine isnt wise, however the flash /ignition point of gas is just about 400C appropriately you craving a naked fire or spark to set it off and Ive used this method for many years without incident. decree your quirk through each viable joint one at a get older and you should find it. I use a slightly flattened piece of brake pipe and some rubber hose from the can of lighter gas to have the funds for a spraying wand and permit a forward blast of gas into each area, especially those difficult to reach considering large implements.
Might as a consequence be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can get a fast deviation find if you unplug the meter and manage the engine without it. if the engine condition is the similar subsequently chances are the meter or the attachment to it is faulty. Its then worth cleaning the MAF sensor wires, as they can get coated past dirt on top of get older which then offsets the reading. Use some entrance cleaner or brake cleaner to spray onto the wires to remove the dirt upon no account adjoin the wires later everything as they are agreed fragile
This could be a large vacuum leak ,with the MAF associated it is isolated measuring the freshen that is getting in the same way as the MAF, correspondingly if the intake manifold is sucking in air the air to fuel ratio will be extremely out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. behind carb cleaner spray spray in the area of the hissing next the engine management and taking into consideration you hear the engine stall or rev innovative there is the leak ,could be a bad vacuum hose bad gasket upon the manifold.
