hey everyone, i was wondering if anyone could help me out here,
I've recently changed my spark plugs, and i'm getting now bad misfiring and bopping sounds when i accelerate, but when i put my old sparkies in, the bopping sound and misfiring stops..
i'm not sure if my old sparkies have been gapped but what should the gap size be in a stock 93' r33gtst?
i've also bought a different set of sparkies just to see if the ones i bought were faulty, but yet again, same outcome..
