1994 4x4 1500 with 350 engine, motor is very sluggish until it runs for 5 min or so and warms up, then runs great. Is the choke not working? Any suggestions on what to look for are appreciated.
Thanks!

No, the choke is not working. In fact, I think it fell off. Sorry, couldn't resist

Seriously though, I would first check the spray pattern from the fuel injectors. They could be more or less just driping gas in if they're dirty.

The spray pattern from the injectors appears to be fine. What else should I look at?

Engine coolant temp sensor not working properly? Worn EGR valve or EGR solenoid? Vacuum leak?
