Help with engine code "G" signal ?
 

Hello everyone I like some advise from any techs out there on how to check the "G" signal from the distributor. I had like 4 different codes. Now I'm down to one but this one is giving me a hard time. Does any body know about the "G" signal from the distributor to the computer ? I can not remember how it is supost to work. I need to check the circuit and I got the diagram and everything! one cable goes to ground, the other one to the computer and the other one to the main relay. There is also a NE signal from the distributor too if that rings any bells ?? The car runs, but it runs like crap, I think it has something to do with the timing, I'm goin to work on the car today.
By the way I have to mention that I have a 1990 Mazda 323 with a 5 sp trainy and a 1.8 L BP TwinCam engine in it. So I finally finished my project. Next will be the rear disk brakes.

THanks in advance

Keep up the good torque
