As its a mechanical fault it tends not to direction on the deformity spacious and you can sometimes hear a hissing noise similar to the engine running.

Thanks for your response. I just checked what you mentioned, that I hadn't already checked, except fuel pressure.Let me say you a tiny more not quite the misery history. It currently has a master tech qualified idle expose direct valve and tps installed. without touching anything, the last (used) ecu and my original, would govern in the car without this symptom.
Hello the TPS does have an effect on switching the car into idle mode appropriately I'd suggest to create certain the throttle plate is 100% closed and not slightly beached considering carbon. and subsequently adjust the TPS in view of that that the IDL pin is continuous to the E2 fasten following the throttle is closed, and entre circuit afterward the throttle is just cracked. Don't distress not quite any voltages, the IDL gain access to is the truly important one.
