Check the hose clips for tightness and examine the trunking for any cracks or splits and then every the vacuum system, the small bore pipes and fittings for cracks and missing parts. The best habit to find a leak is to have the engine doling out and warm and then spray lighter gas /propane or brake cleaner nearly 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 hardship history. It currently has a master tech certified idle air manage 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 plus an intermittent popping hermetic coming at idle.
