A31 Wasted Spark Issues

[Shaaunyb]

Hey guys,

Not a skyline but close enough lol got a 20de A31 running a wasted spark set up (old owner chucked it in) it drops down to 5 cylinders every now and again. Does it more when it's warmed up than when it's cold, tried switching out the ignitor pack but the one I got was a dud and wouldn't fire at all.

Any ideas as to what it could be? Going to try the ignitor pack again once I sus one that works haha

Either ignitor, coils, plugs, leads, wiring, injector.

Are you able to narrow it down to a cylinder by pulling off a lead?

I could do later on, hoping its just the ignitor. Its been looked at a few times before & know its not the wiring
