There's not any one sign. Well not going into diagnostic mode is a pretty good give away. If you can pull codes then you are likely looking somewhere else. Have you gone through the surging idle checklist?

I have absolutly no idea how to check for code. Some make it sound easy but I can't figure it out..... Its just a reocurring problem with idle surge and the occassional bogg, engine feels like its shaking on hard acceleration. can't figure it out

Fwiw that doesn't sound like your computer. Go to the tech stickies and run through the surging idle checklist

Look up jrickers how to on pulling codes.

A miss is usually not a computer problem, more than likely ignition related.
