2000 Infiniti I30 Question: IDLE CONTROL SENSOR?
idles rough when first start and sometimes dies. Car revs up when let off the gas, such as turning corners or coasting at low speed - RPM jumps up and feels like the gear is in neutral then goes back to normal. Check engine light code came up as idle control sensor, but when mechanic put it on the diagnostic machine, it indidicate everything is ok. its obvious its not. - mschrader
When the mechanic used a scanner to retrieve codes did he experience the problem you describe. The idle air control motor is just beneath the throttle housing and is controlled by the fuel injection computer. You need to get someone to drive the car with you so you can demonstrate the problem. Things that can cause a rough idle and stalling can be vacuum leaks, if the mechanic looked at freeze frame information in the scantool valuable diagnostic information is there. A vacuum leak may be seen in long and short term fuel trim figures. Ignition failure or vacuum leaks are the most common failure but the mechanic should have interpreted this from freeze frame information when using the scantool. - patrick mannion
