ok my car is throwin code 8 TOP DEAD CENTER,and i fix it,so i wanna how bad or is it bad to drive on it wit that code

 

Try to replace the distributor. The TDC center is a magnetic pickup in the dizzy.

 

ok i tryed a new dizzy and ECU but i need the car so how bad or will it **** up my motor and if so how bad

 

Replacing the dizzy and/or the ECU didn't work? Try another dizzy. Highly doubt its the ECU.

 

This code will cause the car to run in open loop or limp mode. It may not have any short term problems but in the long term the car will run as rich as the ecu can due to the fact the ecu does not know what is going on with the motor. I would just suggest that you fix the problem. I mean hell the car is telling you where to look and what to fix. I dont think it can be any easier.
Good luck.
