Check the hose clips for tightness and examine the trunking for any cracks or splits and as well as all the vacuum system, the little bore pipes and fittings for cracks and missing parts. The best exaggeration to locate a leak is to have the engine handing out and hot and later spray can lighter gas /propane or brake cleaner not far off from each joint in turn. If the engine rev s taking place you ve found your leak.
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 nearly the hardship history. It currently has a master tech approved 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. behind the MAF is plugged in subsequently the car will stall unless I put my foot upon the accelerator. There is moreover an intermittent popping sealed coming at idle.
