Rough Idle, Misfire

[Jeffz]

I went out Thursday night and my Phazer ran awesome. It sat in the garage over night and when I started it Friday night, it would idle erratically and sounded like it was misfiring. When it's on the trail it runs just fine with a slight over-rev when you punch from from a stop, but always backs down to 11,400 or 11,500. It had a little trouble starting again this morning and is still idling funny. Donuts are good and plugs should be good but not 100% sure. No codes, either. Any suggestions?

It just flashed a code 33 at me, then went away. Runs like crap off idle, then runs fine on top.

Cylinder #1 Ignition Coil (Faulty Ignition) is what the code 33 means. You can read the rest of the description here: http://www.ty4stroke.com/viewtopic.php?t=67046 Its a sticky at the top of the forum. Hope that helps, I'm sure someone here will have more info too .

I figured it out and went riding all day. No dialectic grease in the coils which caused a bad connection to the plugs. I put over 100 miles on today with no more problems!
