so, i drove my car for the second time last night in a year... and it was actin kinda funny for a while... when it was in the warming up stage, if you gave it more than 10% throttle, it would start missing badly on one cylinder, and it would miss after it warmed up, but not as badly (or it didn't seem that bad) around 6200-6500... any ideas or any suggestions on what to check?
