Now you might think that spraying lighter gas on a warm engine isnt wise, however the flash /ignition tapering off of gas is virtually 400C therefore you habit a naked ember or spark to set it off and Ive used this method for many years without incident. be in your habit through each feasible joint one at a get older and you should find it. I use a slightly flattened fragment of brake pipe and some rubber hose from the can of lighter gas to have enough money a spraying wand and allow a take up blast of gas into each area, especially those hard to reach in imitation of large implements.
Its after that 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 result in insufficient fuel visceral delivered to the engine. Might plus be worth cleaning out the idle swiftness control motor / valve as these acquire clogged going on past 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. considering the MAF is plugged in then the car will stall unless I put my foot on the accelerator. There is along with an intermittent popping sealed coming at idle.
