1993 chevy blazer T10 4WD, just replaced water pump and heater core within two weeks of eachother. Added some fuel injector cleaner and now it starts hard and when it runs until it gets hot, it will start chugging when I brake. Almost feels like it will die until I completely stop, when completely stopped it will idle very hard after braking until I get accelerating again.
thanks for your help Brad D.

Check the fuel pressure if its within specs and clean out the idle air control valve and EGR/PCV valves and see what happens-also test the throttle position and manifold absolute pressure sensors
