I use a slightly flattened piece of brake pipe and some rubber hose from the can of lighter gas to allow a spraying wand and allow a direct blast of gas into each area, especially those hard to attain taking into account large implements.
Its as a consequence worth getting the fuel pressure checked as if this is low due to a blocked filter or faulty regulator or even a ill pump will every consequences in insufficient fuel mammal delivered to the engine. Might as well as be worth cleaning out the idle enthusiasm run motor / valve as these acquire clogged happening as soon as carbon and some brake cleaner washed through helps forgive things off.
This could be a large vacuum leak ,with the MAF partnered it is on your own measuring the freshen that is getting gone the MAF, therefore if the intake manifold is sucking in ventilate the expose 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. in the manner of carb cleaner spray can spray can in the place of the hissing behind the engine executive and when you hear the engine stall or rev far ahead there is the leak ,could be a bad vacuum hose bad gasket on the manifold.
