Now you might think that spraying lighter gas not far off from a warm engine isnt wise, however the flash /ignition point of gas is nearly 400C therefore you craving a naked blaze or spark to set it off and Ive used this method for many years without incident. play your pretension through each reachable joint one at a become old and you should locate it. I use a slightly flattened piece of brake pipe and some rubber hose from the can of lighter gas to offer a spraying wand and permit a focus on blast of gas into each area, especially those hard to reach next large implements.
Its then worth getting the fuel pressure checked as if this is low due to a blocked filter or faulty regulator or even a not at your best pump will every repercussion in insufficient fuel creature delivered to the engine. Might furthermore be worth cleaning out the idle speed run motor / valve as these get clogged taking place later than carbon and some brake cleaner washed through helps pardon things off.
I don't have any check engine lights unless I unplug the MAF sensor. subsequently the MAF is plugged in then the car will stall unless I put my foot upon the accelerator. There is moreover an intermittent popping hermetic coming at idle.
