One or more of the OBDII Diagnostic Monitors has not yet cleared. This is usually due the fact that driving conditions have not been correct to allow a monitor tor run to completion. Try driving some more and recheck.

Do not reset the PCM memory - every time you do, the monitors will also be reset and will need to run again. The recent switch back to the stock tune is what caused the current P1000.

Aside from my switching tunes question, I have another. If I changed my tire size on the test tune, changed to stock then put another tune would I have to re input my new tire size?
