This could be an airleak after the airflow meter, any let breathe dragged in here isn t seen by the ECU and fittingly not compensated for and can thin the engine out and can then allow the engine to rev going on taking into account not desired causing coarse running. As its a mechanical oddity it tends not to approach upon the anomaly blithe and you can sometimes hear a hissing noise behind the engine running.
I'm 1500 too high.. or more. It's boggling to me how this trouble has morphed into various idle problems and has everyone perplexed.. or for that reason it seems.

Hello the TPS does have an effect on switching the car into idle mode fittingly I'd suggest to create positive the throttle plate is 100% closed and not slightly beached in imitation of carbon. and subsequently adjust the TPS consequently that the IDL stick is continuous to the E2 pin next the throttle is closed, and way in circuit similar to the throttle is just cracked. Don't worry more or less any voltages, the IDL get into is the in reality important one.
