yeah, I was just gonna pop on here and tell you I saw those plugs at Advance last night while I was looking for an exhaust tip. you know, to gain 15 extra horsepower.

plugs were in the little hardware section for future reference.

as for rough idle, did you go through the setup and lean best idle adjustments?

another thing to consider is checking for a vacuum leak. a vacuum leak can cause rough idle.
