To clear PCM:
Fuse box under hood - adjacent battery.
Remove fuses #4 & #11 for about 5 minutes while you check your oil, or brush some dust off the car, or get your groove on in your driveway.
Re-install fuses. Take your car for a nice leasurely drive to the mall for lunch. I mean leasurely, like you're a tourist taking in the sights & let your car warm up to normal operating temperature. Then drive home - DONE.
There are more detailed methods to get the PCM to re-learn, but it seems to work out the same to me.
