I have a 99 Civic with a 99 GSR engine converted to OBD-1. The other day the CEL same on, It was code 8: TDC . I had the same code 3 weeks ago. The dizzy was replaced. My friend did some research and found out it could either be a wire under the dizzy cap between 2 screws or the wires for the plug that plugs to the dizzy could be bad. He said I should check the resistance between these to slots on the top of the plug. He said the resistance should be between 300 and 350. Does that sound right? What else could it be?
