1998 ford escort zx2 car runs great till it reachs normal operating temp range then it misses like crazy. put in a new fuel pump that didnt help tried new coil pack that didnt help either its not over heating either. it seems like somting electrical is getting hot and once the car warms up whatever is getting hot gets really hot then it misses like crazy if i drive it late at night i or on a cold morning i can drive maybe 10 miles or more before it starts missing but if its in the daytime im lucky if it goes 4 miles
