Check the hose clips for tightness and examine the trunking for any cracks or splits and as a consequence all the vacuum system, the little bore pipes and fittings for cracks and missing parts. The best pretentiousness to find a leak is to have the engine supervision and warm and next spray lighter gas /propane or brake cleaner as regards each joint in turn. If the engine rev s happening 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 say you a little more not quite the trouble history. It currently has a master tech attributed idle ventilate direct valve and tps installed. without disturbing 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 thus I'd recommend to make positive the throttle dish is 100% closed and not slightly beached subsequent to carbon. and later get used to the TPS fittingly that the IDL stick is continuous to the E2 pin taking into account the throttle is closed, and edit circuit behind the throttle is just cracked. Don't bother just about any voltages, the IDL read is the truly important one.
