Hi sim559,
You did not really give us much information on your issue. Are you seeing a check engine light?
If so that would indicate a possible issue, usually the best bet would be to hit a local Autozone, Orielly, etc... and have them pull codes and reset the computer.
You can also reset the computer by disconnecting the battery but I would pull the codes first and check those first.
