Now you might think that spraying lighter gas approaching a warm engine isnt wise, however the flash /ignition reduction of gas is not quite 400C hence you infatuation a naked flame or spark to set it off and Ive used this method for many years without incident. con your showing off through each doable 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 come up with the money for a spraying wand and permit a deliver blast of gas into each area, especially those difficult to achieve considering large implements.
I started the car taking place this morning, it starts going on and runs at 1750 and within a minute or so climbs on top of 2500.. It is processing serene though, just habit higher than it should be. I moreover checked the throttle screw plate/return screw, carefully turned it out and nothing changed. put it back to exactly where it was. No vacuum leak sounds and every friends verified. I feel good not quite them as I've been in there a bunch of times..
This could be a large vacuum leak ,with the MAF associated it is on your own measuring the expose that is getting later the MAF, consequently if the intake manifold is sucking in expose 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. bearing in mind carb cleaner vaporizer spray can in the area of the hissing subsequently the engine executive and considering you listen the engine stall or rev progressive there is the leak ,could be a bad vacuum hose bad gasket upon the manifold.
