I've got a 95 3.4 with 206000 mi. on it. to the best of my knowledge the coil packs have never been changed on it. would it be a good idea to replace those since they have never been changed? i was thinking of getting the msd blasters. also would that make any noticable difference?

 

If there is no misfire, replacing the coils will do little, except to lighten your wallet.
