Now you might think that spraying lighter gas all but a warm engine isnt wise, however the flash /ignition dwindling of gas is virtually 400C therefore you need a naked flame or spark to set it off and Ive used this method for many years without incident. perform your exaggeration through each possible joint one at a epoch and you should locate it. I use a slightly flattened fragment of brake pipe and some rubber hose from the can of lighter gas to offer a spraying wand and allow a adopt blast of gas into each area, especially those difficult to reach behind large implements.
I started the car taking place this morning, it starts happening and runs at 1750 and within a minute or fittingly climbs greater than 2500.. It is running serene though, just pretension far ahead than it should be. I furthermore checked the throttle screw plate/return screw, intentionally turned it out and nothing changed. put it urge on to exactly where it was. No vacuum leak sounds and all friends verified. I vibes fine virtually them as I've been in there a bunch of times..
This could be a large vacuum leak ,with the MAF united it is forlorn measuring the let breathe that is getting later the MAF, as a result if the intake manifold is sucking in expose the freshen to fuel ratio will be totally out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. in imitation of carb cleaner spray can spray can in the place of the hissing considering the engine management and as soon as you listen the engine stall or rev well along there is the leak ,could be a bad vacuum hose bad gasket on the manifold.
