Check the hose clips for tightness and inspect the trunking for any cracks or splits and afterward every the vacuum system, the little bore pipes and fittings for cracks and missing parts. The best artifice to find a leak is to have the engine admin and warm and later vaporizer lighter gas /propane or brake cleaner on the subject of each joint in turn. If the engine rev s in the works 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 tell you a tiny more roughly the misery history. It currently has a master tech approved idle ventilate direct valve and tps installed. without moving anything, the last (used) ecu and my original, would run in the car without this symptom.
I don't have any check engine lights unless I unplug the MAF sensor. next the MAF is plugged in then the car will stall unless I put my foot on the accelerator. There is also an intermittent popping sound coming at idle.
