I'll change the OVP tonight. I have a spare one with the double fuses. Then I'll give the car back to my Dad, because the problem only manifests while he's driving.

I downloaded the tutorial on checking codes for this model. However, the car was bought in Arizona and only has wires on pins 1, 6, and 7. So I don't think I can get any worthwhile info from the codes.

Thanks for the advice guys. If anyone has any other suggestions please chime in.
