Resetting the APPS causes the ECM to 're-learn' where the throttle is at all times when something happens to cause the ECM to not understand what the APPS is telling it like a dirty spot or something like that. What you do is disconnect BOTH batteries (yes you will need to reprogram your radio), turn the key on and wait for atleast 10 minutes, then turn the key off and hook up the batteries. Once that is done turn the key on but don't start it yet. SLOWLY and steadily push the throttle to the floor and SLOWLY and steadily release it. Turn the key off and then you can start it. You have now re-set the APPS.

, I looked at it twice and so did another fellow gearhead. We both agreed that it was a D, but I have had no other problems withit since so I guess that it amounted to nothing.
