I put money on the plug wires. Happened to me before. i chased around that problem around for a while and it ended up being the wires.

 

I don't know anything about this issue, but I was talking with my local shop that specializes in Evo's about my clutch decision, and they recommended I avoid a lightened flywheel because it could cause misfires. I didn't ask why, but they've done a ton of Evo's so I assume it's from experience...

 

i have a lw flywheel and have had 0 misfire issues.

 

have you figured this out yet? good luck
