Check the hose clips for tightness and examine the trunking for any cracks or splits and next all the vacuum system, the small bore pipes and fittings for cracks and missing parts. The best pretension to find a leak is to have the engine organization and warm and subsequently spray lighter gas /propane or brake cleaner regarding each joint in turn. If the engine rev s up 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 more or less the misery history. It currently has a master tech recognized idle air govern valve and tps installed. without moving anything, the last (used) ecu and my original, would rule in the car without this symptom.
Hello the TPS does have an effect upon switching the car into idle mode so I'd recommend to make positive the throttle plate is 100% closed and not slightly stuck subsequently carbon. and after that get used to the TPS consequently that the IDL stick is continuous to the E2 fix in imitation of the throttle is closed, and entre circuit similar to the throttle is just cracked. Don't upset practically any voltages, the IDL open is the truly important one.
