Now you might think that spraying lighter gas in relation to a hot engine isnt wise, however the flash /ignition point of gas is not quite 400C in view of that you need a naked fire or spark to set it off and Ive used this method for many years without incident. piece of legislation your showing off through each viable joint one at a become old 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 have the funds for a spraying wand and allow a tackle blast of gas into each area, especially those hard to attain like large implements.
I started the car up this morning, it starts in the works and runs at 1750 and within a minute or in view of that climbs more than 2500.. It is supervision smooth though, just quirk complex than it should be. I plus checked the throttle screw plate/return screw, intentionally turned it out and nothing changed. put it incite to exactly where it was. No vacuum leak sounds and every contacts verified. I quality good more or less them as I've been in there a bunch of times..
This could be a large vacuum leak ,with the MAF aligned it is on your own measuring the ventilate that is getting once the MAF, consequently if the intake manifold is sucking in expose the ventilate to fuel ratio will be certainly out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. taking into consideration carb cleaner spray spray can in the area of the hissing bearing in mind the engine handing out and in imitation of you hear the engine stall or rev far along there is the leak ,could be a bad vacuum hose bad gasket on the manifold.
