Check the hose clips for tightness and examine the trunking for any cracks or splits and next every the vacuum system, the small bore pipes and fittings for cracks and missing parts. The best pretentiousness to locate a leak is to have the engine direction and hot and later spray can lighter gas /propane or brake cleaner roughly 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 say you a tiny more about the suffering history. It currently has a master tech attributed idle air rule valve and tps installed. without disturbing anything, the last (used) ecu and my original, would control in the car without this symptom.
Hello the TPS does have an effect upon switching the car into idle mode consequently I'd recommend to make definite the throttle dish is 100% closed and not slightly stranded similar to carbon. and next get used to the TPS fittingly that the IDL fix is continuous to the E2 fix in the manner of the throttle is closed, and entrance circuit taking into consideration the throttle is just cracked. Don't worry approximately any voltages, the IDL admission is the really important one.
