Default Re: Hard Misfire Under Load plugs changed

My 03 PT Turbo had the misfire issue around 37K (just past the bumper to bumper anyway) at the time I replaced the wires with Bosch spiral cores and changed the plugs to Champion Platinum tip (no one in my area stocks anything for the Turbo PT's but platium or iridium tip plugs). That fixed the problem for about 10k miles. At that time I replaced the plugs again but this time I used Autolite Platinum (Very good luck with Autolite in my other vehicles). Again everything was good for about 10k miles and the misfire under load came back.

I didn't know about the TSB recommending the plug gap be reduced but I had figured I would try a smaller gap to see what it would do. Since all my other vehicles recommend about 0.035" I went with that gap. Again the misfire has been corrected.

My question is has anyone used the MSD Blaster coil and 8.5 MSD wires on there turbo motor? I have had good luck with MSD ignition parts on my Barracuda.

Also, what do folks recommend for plugs? I have had a turbo mopar continuously since I got my first Daytona Turbo in 85. The general consensus has always been that turbo motors are happier with plain copper core plugs and the fact that the PT came with copper cores would suggest that may be true since most other mopars now come with platinum tip plugs.
