Now you might think that spraying lighter gas approaching a warm engine isnt wise, however the flash /ignition dwindling of gas is very nearly 400C suitably you habit a naked fire or spark to set it off and Ive used this method for many years without incident. pretend your way through each viable joint one at a times 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 permit a speak to blast of gas into each area, especially those hard to reach next large implements.
Thanks for your response. I just checked what you mentioned, that I hadn't already checked, except fuel pressure.Let me tell you a little more about the misfortune history. It currently has a master tech attributed idle let breathe run valve and tps installed. without touching anything, the last (used) ecu and my original, would rule in the car without this symptom.
I don't have any check engine lights unless I unplug the MAF sensor. similar to the MAF is plugged in then the car will stall unless I put my foot on the accelerator. There is moreover an intermittent popping sound coming at idle.
