Fast Idle Problem
Posted 07 January 2004 - 08:03 PM
One curious difference -- his other customer had a Check Engine light. I do not. I did get a Check Engine light about a week after this problem appeared, but it coincided with the Speed Sensor crapping out (speedo was reading zero). Fixing the Speed Sensor fixed the speedo and resolved the Check Engine light, but I still have a fast idle. Has anybody seen this before?

Then he started doing a little research on the car's computer. Somewhere in his reference he found that when you change a part like the idle relief valve, you need to disconnect the battery to zero the computer's memory, since it will have decided (after several weeks of idling too fast) that the fast idle speed is the correct one.
We disconnected the battery, let it stand 5 minutes, reconnected it, and it idled completely normally. I'm doubly happy about this because I was beginning to wonder if I'd shelled out $300+ for nothing.
