Check the hose clips for tightness and examine the trunking for any cracks or splits and also all the vacuum system, the little bore pipes and fittings for cracks and missing parts. The best quirk to find a leak is to have the engine management and warm and later vaporizer lighter gas /propane or brake cleaner approximately each joint in turn. If the engine rev s stirring 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 hardship history. It currently has a master tech attributed idle freshen run valve and tps installed. without disturbing anything, the last (used) ecu and my original, would direct in the car without this symptom.
Hello the TPS does have an effect upon switching the car into idle mode correspondingly I'd recommend to create certain the throttle plate is 100% closed and not slightly grounded subsequent to carbon. and later accustom yourself the TPS as a result that the IDL glue is continuous to the E2 fasten later the throttle is closed, and log on circuit with the throttle is just cracked. Don't make miserable just about any voltages, the IDL right of entry is the in fact important one.
