Now you might think that spraying lighter gas approximately a warm engine isnt wise, however the flash /ignition point of gas is just about 400C consequently you obsession a naked flare or spark to set it off and Ive used this method for many years without incident. conduct yourself your showing off through each reachable 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 manage to pay for a spraying wand and allow a dispatch blast of gas into each area, especially those hard to achieve afterward large implements.
Its furthermore 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 outcome in insufficient fuel living thing delivered to the engine. Might along with be worth cleaning out the idle keenness govern motor / valve as these acquire clogged stirring gone carbon and some brake cleaner washed through helps clear things off.
I don't have any check engine lights unless I unplug the MAF sensor. like the MAF is plugged in subsequently the car will stall unless I put my foot upon the accelerator. There is in addition to an intermittent popping strong coming at idle.
