Question Rough Idle or something else?

I have a 1993 351W mostly stock other than exhaust and not cat, but recently I have had problems with my truck shaking like it has a bad idle, I put a new Harm balancer not to long ago and I replaced both motor mounts and tranny mount but I can feel my truck shaking bad enough I can feel it in my arm rest, only does it when i'm in park or stoped at a light other than that it doesnt shake while i'm driving. I'm going to change plugs, wires and rotor cap. I cleaned my IAC but did not replace it. Also I have a feeling my map sensor is bad cause of rough starts in early morning and very rich smelling exhaust and suggestions would be helpful.. Thank you.

pull codes to check for any fuel type sensors going bad. You also might try cleaning your throttle body out. It is fairly simple and very effective when it comes to Idle and acceleration issues.
