Now you might think that spraying lighter gas re a warm engine isnt wise, however the flash /ignition lessening of gas is virtually 400C as a result you need a naked ember or spark to set it off and Ive used this method for many years without incident. enactment your habit through each viable joint one at a time and you should find it. I use a slightly flattened fragment of brake pipe and some rubber hose from the can of lighter gas to find the money for a spraying wand and allow a adopt blast of gas into each area, especially those difficult to accomplish in the same way as large implements.
Might furthermore be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can realize a fast fault find if you unplug the meter and govern the engine without it. if the engine condition is the similar subsequently chances are the meter or the relationship to it is faulty. Its moreover worth cleaning the MAF sensor wires, as they can get coated similar to dirt higher than period which later offsets the reading. Use some entry cleaner or brake cleaner to spray onto the wires to surgically remove the dirt on no account touch the wires later than all as they are totally fragile
This could be a large vacuum leak ,with the MAF aligned it is forlorn measuring the air that is getting past the MAF, for that reason if the intake manifold is sucking in expose 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. as soon as carb cleaner vaporizer vaporizer in the place of the hissing bearing in mind the engine supervision and taking into consideration you listen the engine stall or rev complex there is the leak ,could be a bad vacuum hose bad gasket upon the manifold.
