Do you happen to have a '98? If so, the dealer has a PCM reflash, because some 98's have problems falsely displaying this code. Usually happens after a hard up-shift.

You probably still have the firstPCM calibration code. I believe there was 3 updates for the 98, one of them being the P0103 fix. You'll need the dealer to flash the PCM for ya.
