My 85 has this same problem. it misfires until it warms up. Probably a EGR solenoid which I believe to be the same issue as mine. I removed my EGR and installed a plate and it runs better but still have that misfire in the morning. After about 30 seconds it goes away. But if your truck doesnt even have a EGR solenoid then I dont see how that can be the problem.
