I changed my radiator, engine oil, and transmission fluid. After changing the radiator but before chaning the fluids I drove my car to the auto parts stop to get oil and transmission fluid I notice a slight stall when driving. Later after changing the oil and transmission fluids driving home my car started to sputter like it was about to shut off and the engine over heated. When I got home the car shut off and was very hard to restart. But when I put water into the radiator it will start again. Also early in the mornings the car will start and drive normal for 10 min when the engine gets to the normal temp I can feel the car wants to shut off. My check engine light is on and the codes are all four cylinders are mis firing. (I have also changed the spark plugs and harness)
