Exclamation 2005 engine problems and questions

What's going on.
I've got a few problems, a couple of days ago I put seafoam in my gas tank. I stalled out from taking the truck out off drive to park, then to reverse. The next two days I had the check engine on, but it turned off the third day.

I had codes checked on the truck and it came up with engine code 302 (miss fire).

The other day I removed the crankcase cap and added more seafoam. The engine light turned back on, I'm assuming it's the same problem.

Also, it looks like I have gunk on the underside of the crankcase cap and also in the groves which the cap screws into.

Any advice?? Anyone have miss firing problems?

Thanks

Has anyone tried Gunk engine flush? Is Seafoam a good preventative measure for high mileage applications? I have listen to people swear by marvel's mystery oil also. Never used any of this stuff, but always interested in new ways of maintaining.

As in crankcase flushing? Bad idea if that's what you mean.
