Rep Power: 0

I have a '90 Civic Hatchback that will run great for about a half hour and then the CEL comes on and the engine starts to miss and lose power.I let it set for maybe 10 minutes and it starts and runs good again. I checked the ECU code and it blinks 8 times, which indicates that the TDC sensor is bad.I wonder if I should take a chance and try a new ignition coil before I buy a distributor.A bad coil will cause these same symptoms on the older cars that i've owned over the years.
