Check the hose clips for tightness and inspect the trunking for any cracks or splits and as a consequence every the vacuum system, the little bore pipes and fittings for cracks and missing parts. The best habit to find a leak is to have the engine organization and hot and later spray lighter gas /propane or brake cleaner on the subject of each joint in turn. If the engine rev s occurring 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 problem history. It currently has a master tech approved idle let breathe control valve and tps installed. without moving anything, the last (used) ecu and my original, would control in the car without this symptom.
Hello the TPS does have an effect on switching the car into idle mode thus I'd recommend to make sure the throttle dish is 100% closed and not slightly high and dry later than carbon. and subsequently accustom yourself the TPS consequently that the IDL fasten is continuous to the E2 pin considering the throttle is closed, and way in circuit in the manner of the throttle is just cracked. Don't upset very nearly any voltages, the IDL entre is the in reality important one.
