I have a problems that I am hoping someone can shed light on.

Maybe the oil pressure sensor has been replaced with the incorrect idiot light sensor or is just shot.

Sounds like the circuit breaker for the headlights is tripping. Something is overloading it and or the driving lights broke the camels back. My fix would be to run a fused wire from the battery to the driving lights that is activated by a relay from the factory wiring. This way you aren't adding a big load to the stock wiring and breaker.

Maybe related to above? not sure.

Sounds like bad connections/ grounds etc. just giving you intermitent problems. A lot of problems related to poor grounds cause erratic behavior as the current finds "sneaky" ways to get to ground by back feeding through other systems. ( If you ever see a car that has its running lights go off when the driver hits the brakes or uses his turn signals this is often caused by poor grounds causing a backfeed which kills the other lights)

Take the aftermarket stereo out of the equation first and see if your maladies disapear or lessen
