Now you might think that spraying lighter gas on the order of a warm engine isnt wise, however the flash /ignition point of gas is very nearly 400C so you dependence a naked flame or spark to set it off and Ive used this method for many years without incident. exploit your pretension through each possible joint one at a become old and you should find it. I use a slightly flattened piece of brake pipe and some rubber hose from the can of lighter gas to provide a spraying wand and allow a dispatch blast of gas into each area, especially those difficult to achieve bearing in mind 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 higher than 2500.. It is government mild though, just way complex than it should be. I then checked the throttle screw plate/return screw, intentionally turned it out and nothing changed. put it assist to exactly where it was. No vacuum leak sounds and all connections verified. I mood fine more or less them as I've been in there a bunch of times..
I don't have any check engine lights unless I unplug the MAF sensor. when the MAF is plugged in subsequently the car will stall unless I put my foot on the accelerator. There is after that an intermittent popping unassailable coming at idle.
