Hesitation and miss

Symptoms;
. 1. Slight miss at idle.
. 2. Will not accelerate unless throttle is darn near floored, and maybe one out of ten times it will seem to function as it should.
. 3. CEL comes on but only intermittently, never at idle.
. 4. Exhaust seems to blow out much harder than my 92 with the 300 and my friends 2006 with the 5.4L.
. 5. Catalytic converter seems too hot to me.

checked;
. 1. Plugs (all good and getting spark).
. 2. All vac lines look good, no hissing.
. 3. Timing is perfect.
. 4. Spray carburetor cleaner all around vac lines, EGR, intake and even the plugs with no change in running.
. 5. Fuel pressure (34 key on and about 37 psi running).
. 6. Compression in tolerance of Haynes manual, I forget what they all were but we are withing 10% of each other.
. * Tried to pull codes, by the way, will not show codes at idle and I think the diagnostic port for the obd 1 is messed up, have tried with and without obd 1 scan tool.

The following are all things that have been replaced (for give my part swapping, as I could not pull codes it was kind of a best guess scenario).

Replaced:
. 1. EGR.
. 2. Fuel pump regulator (old one was bent where vac. Hooked up anyways).
. 3. TPS.
. 4. IAC.
. 5. Fuel filter.
. 6. Throttle body gasket.
. 7. Air filter.
. 8. MAF.
. 9. Battery (kind of unrelated as old one was shot anyways).

The next things on my list to try (unless you fine folks here can help) is to try a new coil and I may hollow out the catalytic converter since it seems to me like it gets much hotter than it should. After this I am at a complete loss (more than before). I have tried not to just throw parts at it, but nothing is seeming to workout right. It is a truck I bought from a friend and he is at a loss too. Any help would be greatly appreciated.
