hi

I have an 87 t2 and i cant get spark on my trailing coils for some reason. My car was not running at all with no spark untill i found a ground under my upper intake mainifold and than i had spark in my leading coils agin. Dose anyone know where the trailing coils are grounded at? or why there wouldn't be working thanks.

 

driving around with your trailing plugs disconnected actually reduces detonation. People have talked about this a bunch of times. Its very true.

 

where is the ground on the manifold? i think maybe thats my problem.let me know something please
