If its steady CEL that comes back after being reset, I would consider running a bottle or two of Techron through and see what happens.

I don't recommend that with a flashing CEL which is much more serious.

Early in my 986 ownership I had a CEL that didn't want to go away. Some Techron and some regular driving cleared up. Once it went away, that was the end if it. Good luck.

Definitely change the ignition switch for random electrical gremlins. I did two (actually 3) on my car over time. I put one in that was bad, so I replaced it again.
