I have a 1997 honda civic manual transmission and yesterday while I was driving the engine didnt over heat but the temperature gage was really high and the engine light came on. So I stopped and saw that the radiator hose had completely disconnected. So I got a new clamp and fixed that but now when im driving the car seems to hickup while im going and when I switch to a higher gear it seems to not want to accelerate or catch the gear. For me to get the car to accelerate like normal I have to rev the engine to about 4000rpms. What is wrong with my car, is it the clutch?
