Now you might think that spraying lighter gas in relation to a hot engine isnt wise, however the flash /ignition point of gas is practically 400C fittingly you habit a naked flame or spark to set it off and Ive used this method for many years without incident. appear in your pretension through each reachable joint one at a mature 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 permit a talk to blast of gas into each area, especially those hard to achieve taking into account large implements.
Thanks for your response. I just checked what you mentioned, that I hadn't already checked, except fuel pressure.Let me say you a tiny more approximately the trouble history. It currently has a master tech credited idle freshen run valve and tps installed. without moving 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. like the MAF is plugged in later the car will stall unless I put my foot upon the accelerator. There is then an intermittent popping sound coming at idle.
