Had that code when I put top engine cleaner in the engine and also a few months ago a mouse chewed one wire near my pcm harness. Fixed the wire and no issues. Look at the wires coming out of you pcm, never know.

I just fixed my problem with my misfire. I tuned it up 2 times and found a manifold leak and it cleared it instantly. So if u do a tune up and it doesn't fix your problem then check for vacuum problems.
