I would check to make shure you have the firing order right first. Make sure your plug wires are tight and not touching the exhaust.

If it's missfiring, get a pair a spark plug wire pliers, very carefully pull each wire off the cap,(DON'T GET ZAPPED!) Wich ever cylinder/cylinders don't make a difference will be the ones missfiring.

Personally I've never had good luck with platinum plugs, I put them in my truck and it ran like crap, put the regular ac delco plugs in and it ran great.
