Check the hose clips for tightness and inspect the trunking for any cracks or splits and afterward all the vacuum system, the little bore pipes and fittings for cracks and missing parts. The best showing off to locate a leak is to have the engine processing and warm and later spray can lighter gas /propane or brake cleaner all but each joint in turn. If the engine rev s taking place 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 approximately the burden history. It currently has a master tech recognized idle ventilate control valve and tps installed. without upsetting anything, the last (used) ecu and my original, would manage in the car without this symptom.
Hello the TPS does have an effect on switching the car into idle mode for that reason I'd recommend to create determined the throttle plate is 100% closed and not slightly beached later carbon. and later accustom yourself the TPS consequently that the IDL fasten is continuous to the E2 attach in the same way as the throttle is closed, and gate circuit later than the throttle is just cracked. Don't cause problems approximately any voltages, the IDL right of entry is the essentially important one.
