This could be an airleak after the airflow meter, any freshen dragged in here isn t seen by the ECU and suitably not compensated for and can lean the engine out and can with allow the engine to rev taking place taking into account not desired causing severe running. As its a mechanical idiosyncrasy it tends not to aim upon the irregularity roomy and you can sometimes hear a hissing noise when the engine running.
Thanks for your response. I just checked what you mentioned, that I hadn't already checked, except fuel pressure.Let me say you a little more more or less the burden history. It currently has a master tech attributed idle expose rule valve and tps installed. without upsetting 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 hence I'd suggest to make positive the throttle dish is 100% closed and not slightly high and dry in imitation of carbon. and after that adapt the TPS in view of that that the IDL fasten is continuous to the E2 glue past the throttle is closed, and door circuit in imitation of the throttle is just cracked. Don't trouble not quite any voltages, the IDL right to use is the essentially important one.
