Check the hose clips for tightness and examine the trunking for any cracks or splits and after that all the vacuum system, the small bore pipes and fittings for cracks and missing parts. The best pretentiousness to find a leak is to have the engine government and hot and subsequently spray lighter gas /propane or brake cleaner with reference to each joint in turn. If the engine rev s stirring 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 govern valve and tps installed. without disturbing 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 correspondingly I'd suggest to make distinct the throttle dish is 100% closed and not slightly high and dry taking into account carbon. and next familiarize the TPS in view of that that the IDL pin is continuous to the E2 fix as soon as the throttle is closed, and door circuit later than the throttle is just cracked. Don't trouble more or less any voltages, the IDL right of entry is the essentially important one.
