Now you might think that spraying lighter gas all but a hot engine isnt wise, however the flash /ignition tapering off of gas is about 400C suitably you habit a naked ember or spark to set it off and Ive used this method for many years without incident. feign your mannerism through each realistic joint one at a period 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 come up with the money for a spraying wand and permit a forward blast of gas into each area, especially those difficult to achieve subsequently 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 sick pump will every repercussion in insufficient fuel beast delivered to the engine. Might with be worth cleaning out the idle promptness govern motor / valve as these get clogged occurring gone carbon and some brake cleaner washed through helps free things off.
I don't have any check engine lights unless I unplug the MAF sensor. behind the MAF is plugged in then the car will stall unless I put my foot on the accelerator. There is as a consequence an intermittent popping solid coming at idle.
