Troubleshooting
1

Hello all my name is:
I have a: (GTO, 3000GT, STEALTH / SL, MR, VR4, TT)
It has the following issue: im only getting spark on 4 of 6 plugs. I have replaced all coils and ptu and the problem still exists.

NO HELP WILL BE GIVEN WITHOUT PROVIDING AS MUCH INFORMATION AS POSSIBLE RELATING TO YOUR ISSUE

If the plugs, leads, coils and PTU are all confirmed as working then really the only other thing is the ECU or the signal wires from ECU to PTU.
