Check the hose clips for tightness and examine the trunking for any cracks or splits and then all the vacuum system, the small bore pipes and fittings for cracks and missing parts. The best exaggeration to find a leak is to have the engine direction and warm and subsequently spray can lighter gas /propane or brake cleaner as regards each joint in turn. If the engine rev s occurring 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 little more more or less the suffering history. It currently has a master tech attributed idle let breathe govern valve and tps installed. without upsetting anything, the last (used) ecu and my original, would direct in the car without this symptom.
I don't have any check engine lights unless I unplug the MAF sensor. afterward the MAF is plugged in then the car will stall unless I put my foot on the accelerator. There is as well as an intermittent popping hermetically sealed coming at idle.
