Here is a log of the cold start http://datazap.me/u/bigdaddyaaron/lo...ta=17-18-24-25

Recently, I developed a misfire on cold starts. The log shows bank 2 being sporadic in both stft and afr. On one cold start, the dme threw a code for a misfire on cly 4. Once the rpm's drop after 20 or so seconds, the car idles and drives normally. Any idea as to what may be happening?
