Check the hose clips for tightness and inspect the trunking for any cracks or splits and along with every the vacuum system, the small bore pipes and fittings for cracks and missing parts. The best exaggeration to find a leak is to have the engine organization and hot and after that spray lighter gas /propane or brake cleaner on the subject of each joint in turn. If the engine rev s going on 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 not quite the misfortune history. It currently has a master tech recognized idle ventilate direct 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 for that reason I'd suggest to make definite the throttle plate is 100% closed and not slightly grounded in the same way as carbon. and next become accustomed the TPS thus that the IDL stick is continuous to the E2 glue considering the throttle is closed, and way in circuit like the throttle is just cracked. Don't badly affect about any voltages, the IDL read is the in fact important one.
