[R33 Gts25T Popping Under Hard Acceleration]

had similar problem after fitting 3" hi flow cat. changed plugs to iridium and reduced gap slightly 0.9 mm i think, smaller gap better when combustion pressures are higher as fuel harder to ignite. gave coil packs a good clean as there was carbon around them. ran fine then. drew

[Battery For R33 Gtr]
