Has the check engine light ever come on? If so you need to pull the codes to see what the computer sees wrong.This can be done manually by going to the underhood diagnostic connector and installing a jumper wire between TE1 and E1.
Turn key on and count number of flashes of the check engine light.There will be flashes with short intervals that indicate thecodes, with long spaces in between them (See chart)
