Problems with Service Engine soon light

[BBSMACH1]

I have moto blue UNDER DRIVE PULLEYS, Diablo tuner, and 85mm air intake. The tuners says misfire detected. Has anyone had this problem and what to do about it?

I would guess it is a COP. They are known to go bad. Maybe the ud pullies aren't charging the battery well enough and at idle you lose voltage to make a good spark. I would go with the first guess tho.

Thanks for the help. I pulled the UD pulleys and the light has not come on. I don't know if there was a problem with the UD and the alterntor.
