Check the hose clips for tightness and inspect the trunking for any cracks or splits and moreover all the vacuum system, the little bore pipes and fittings for cracks and missing parts. The best pretentiousness to locate a leak is to have the engine management and hot and later vaporizer lighter gas /propane or brake cleaner something like 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 tell you a little more more or less the misfortune history. It currently has a master tech official idle air run valve and tps installed. without touching 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 correspondingly I'd recommend to make clear the throttle dish is 100% closed and not slightly beached when carbon. and later familiarize the TPS in view of that that the IDL glue is continuous to the E2 pin as soon as the throttle is closed, and gain access to circuit following the throttle is just cracked. Don't upset roughly any voltages, the IDL contact is the in reality important one.
