Check the hose clips for tightness and inspect the trunking for any cracks or splits and in addition to every the vacuum system, the small bore pipes and fittings for cracks and missing parts. The best exaggeration to locate a leak is to have the engine running and warm and subsequently vaporizer lighter gas /propane or brake cleaner on the order of 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 about the trouble history. It currently has a master tech recognized idle air rule valve and tps installed. without heartwarming anything, the last (used) ecu and my original, would govern in the car without this symptom.
Hello the TPS does have an effect upon switching the car into idle mode therefore I'd recommend to create distinct the throttle plate is 100% closed and not slightly beached bearing in mind carbon. and subsequently adjust the TPS therefore that the IDL glue is continuous to the E2 stick in imitation of the throttle is closed, and right to use circuit taking into account the throttle is just cracked. Don't bother about any voltages, the IDL gain access to is the in point of fact important one.
