ive searched but none of the answers were clear so ima post it here i have a 94 civic cx ok heres the story after driving for short periods and the car not really warmed up to normal drivin temp but i will come to a stop at lets say a red light and my car will shut off on me and not start until cooled down for 20min...so im just wonderin could it be my main relay, or dizzy and all the stuff inside it like the coil and module? its really embarrasing to have to push ur car to the side when this happens someone help
