Engine misfire
Drove my truck 92 in sig to the beach 60 miles ran fine. Drive it home last night and it ran fine again until I got off the freeway. As I came to the signal it had a pretty bad misfire/rough idle. Once you get above the 1200-1500 rpm range you cannot feel it at all and it runs fine. New plugs, wires, cap and rotor 10,000 miles ago, new iac and fuel filter even less then that. No codes relating to this at all.

I guess if it was me, based on what you've said, I might think back to where I got my last load of fuel.
Since I just got off the highway, and the EGR is open for an extended period, I might wonder if it had closed right after getting off the highway.
Ignition, spark, or air would be where you'll look for starters.
