It happened to me after I installed my underdrive pulleys. I went ahead and changed the plugs and COPs and had no problems untill today. It kicked back on when I was going about 85 on the highway. I am going to take it in tomorrow. I;ll let you know what they tell me.

P0300 is Random/Multiple cylinder misfire detected. Where did you get your tune, or is it dyno tuned?
