Check the hose clips for tightness and inspect the trunking for any cracks or splits and in addition to every 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 admin and warm and after that spray can lighter gas /propane or brake cleaner in this area each joint in turn. If the engine rev s in the works 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 approximately the pain history. It currently has a master tech approved idle air rule valve and tps installed. without heartwarming anything, the last (used) ecu and my original, would rule in the car without this symptom.
Hello the TPS does have an effect upon switching the car into idle mode suitably I'd recommend to create positive the throttle dish is 100% closed and not slightly grounded with carbon. and then become accustomed the TPS so that the IDL glue is continuous to the E2 glue later than the throttle is closed, and admission circuit in imitation of the throttle is just cracked. Don't trouble roughly any voltages, the IDL entry is the in point of fact important one.
