Hi,
i have a nissan 300zx 1994 3litre non turbo, having really bad idle problems
when started it fires upto 3k up and down.
Tap on the throttle and goes to redline so isnt driveable
ive located the icv sensor i disconnected the eletrical connection and stilll does the same thing, does this mean it is not the sensor ?
checked for vacumn leaks etc had no joy
before i start work on it i was wondering if there is any common faults
thanks
