Problems Please Help

I put new plugs in my r 33 last weekend and after 4 days it decided to missfire over all rev ranges i have pulled out the coilpacks and unplugged them and it still missfires does this mean i have more than one coilpack breaking down? how can i test this? when idle on 5 cylinders it still misses abit. i pulled out a few coilpacks and there is markings on the side of a few of the packs how can fix this problem please?

Try checking your plugs........are they Iridium plugs or just normal ones? also make sure they are gapped correctly ie: .8 mm, If all good there then must be coilpacks i guess!

Exactly as deluxe said, I have had issues with irridium plugs in the past. Also had misfire in my old R32 which we traced to the ignition module.... approx. $250 to replace.

Yea got some new iridum plugs in it and new Splitfire coils fixed it slightly but still does it sounds like something it could be the ignition module bit of a pain when ur driving to macas and it all goes 30 metres down the road
