Please help!! My Cheetah developed a intermittent mag on no2 when I drop no 1 mag. Where do I start looking for the problem??

Mine also had the problem.It is somewhere at the wiring loom at the 2 ignition coils.Cant remember exactly but when I pulled on the wiring harness there was a broken wire

Also check your earths, they should be in two different places on the manifold, rear right. One might have come loose. I am not talking about the earth used to kill the ignition, rather the earth for the ignition unit.
