So the check engine light keeps coming on and then going off. And when I come to a stop the oil pressure light comes on and every once in a while it dies. Any suggestions on where to start?

 

Two separate problems.... Oil pressure is likely just the sensor. They are pretty notorious for going bad....... Sure sign is, if you even slightly bump the gas, and pressure comes back up to something reasonable, that's a bad sensor.

For the CEL, need to know what code it is throwing.
