This could be an airleak after the airflow meter, any expose dragged in here isn t seen by the ECU and for that reason not compensated for and can lean the engine out and can along with allow the engine to rev taking place when not desired causing aggressive running. As its a mechanical fault it tends not to position upon the irregularity fresh and you can sometimes hear a hissing noise gone the engine running.

Hello the TPS does have an effect on switching the car into idle mode in view of that I'd recommend to make determined the throttle dish is 100% closed and not slightly stuck afterward carbon. and subsequently acclimatize the TPS suitably that the IDL stick is continuous to the E2 stick afterward the throttle is closed, and right of entry circuit similar to the throttle is just cracked. Don't make miserable more or less any voltages, the IDL entre is the really important one.
