Check the hose clips for tightness and examine the trunking for any cracks or splits and plus every the vacuum system, the small bore pipes and fittings for cracks and missing parts. The best habit to locate a leak is to have the engine direction and warm and next vaporizer lighter gas /propane or brake cleaner on each joint in turn. If the engine rev s happening 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 just about the hardship history. It currently has a master tech ascribed idle freshen rule valve and tps installed. without touching 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. in imitation of the MAF is plugged in next the car will stall unless I put my foot upon the accelerator. There is after that an intermittent popping unassailable coming at idle.
