RE: Engine misses and idles funny when warm but not cold.
Whens the last time you replaced your air filter?????
Under cold idle the puter will kick back the amount of air flowing into the intake, electronically controlled choke.
Once the engine warms up the puter will open up the air intake and changes the timing to compensate. However if your not getting enough air due to a plugged up air filter, it WILL trip the check engine light. Plus it will run fine at higher rpm's. If it were my truck, I'd start with the air filter.
