My 95 Geo Prizm with a 1.6 motor, 3 speed auto trans, AC, and anti lock brakes. This car starts and runs great until it gets about a mile down the road and the motor warms up. Then it seems to be running on 3 cylinders. It does it at the same temperature every time, it's for sure related to a warming motor. HELP! This car only has 40,000 miles on it

Can you feel/hear an actual misfire? Like a cylinder cutting out?

You could try unplug/disconnect EGR and see if that helps?
