Now you might think that spraying lighter gas going on for a warm engine isnt wise, however the flash /ignition dwindling of gas is approximately 400C hence you obsession a naked flame or spark to set it off and Ive used this method for many years without incident. act out your pretension through each realizable joint one at a get older 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 provide a spraying wand and allow a attend to blast of gas into each area, especially those difficult to accomplish once large implements.
Its plus worth getting the fuel pressure checked as if this is low due to a blocked filter or faulty regulator or even a poorly pump will every result in insufficient fuel subconscious delivered to the engine. Might in addition to be worth cleaning out the idle enthusiasm govern motor / valve as these acquire clogged taking place later than carbon and some brake cleaner washed through helps forgive things off.
I don't have any check engine lights unless I unplug the MAF sensor. later than the MAF is plugged in later the car will stall unless I put my foot upon the accelerator. There is moreover an intermittent popping strong coming at idle.
