Nissan Skyline problem


it’s a 1990 nissan skyline RB20, and it’s not running on all 6 cylinders. also misfiring.

anyone have any ideas what might be causing this?


Have you tried a tune-up? And you may need to replace spark plug wires and distributor cap and rotor if equipped.


Almost anything could cause it other than space aliens.

Tell us more. How many miles on the car? How about maintenance? Timing belt, oil changes filers (air, oil and fuel)

Could you tell us exactly what it does or does not do, describe any sounds or missing sounds etc. How long has it been like this. Did it happen suddenly or did it sort of creap up?


It depends. What type is that? (RB20E/RB20DE/RB20DET)
