Check the hose clips for tightness and inspect the trunking for any cracks or splits and with every the vacuum system, the small bore pipes and fittings for cracks and missing parts. The best showing off to locate a leak is to have the engine organization and hot and subsequently spray lighter gas /propane or brake cleaner on 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 tell you a little more practically the misery history. It currently has a master tech ascribed idle expose run valve and tps installed. without moving anything, the last (used) ecu and my original, would run in the car without this symptom.
Hello the TPS does have an effect upon switching the car into idle mode thus I'd suggest to create definite the throttle dish is 100% closed and not slightly high and dry as soon as carbon. and after that accustom yourself the TPS so that the IDL fasten is continuous to the E2 fix in the same way as the throttle is closed, and approach circuit past the throttle is just cracked. Don't upset not quite any voltages, the IDL entre is the essentially important one.
