Out of nowhere my cars idling went up very high
when I start it, goes up to 3000 revs and only goes
down to 2000 revs. Replaced the idling valve, but
still no difference
Have the vehicle scanned for any trouble codes. This will let you know what to look at. Write the codes down. It is possible the Throttle Positioning Sensor could be bad, or the wiring plugin may have some broken wires. Also a bad vacuum leak could be a cause. It just needs to be scanned and looked at.
