Sure could be.

Are you getting any codes? a dying opti will throw a code 16 - low res signal failure.

I would check the coil and coil wire first...

What year? If its an early opti, and the original, 60k miles is pretty good. Optis can fail from time as much as miles.

Have you checked you water pump to see if it's doing its weeping routine. If the water pump has never been replace it could be weeping ever so slightly but just enough do drown the opti.. stick your hands in there to see if you gettin any moisture.

you may have an oil leak, check, you DO have an oil leak.

And it is not uncommon for oil to invade the opti and cause problems.
