Default RE: what to replace first

Well i was able to change the front passenger side o2 sensor this weekend. I eliminated some of the codes. Now i'm down to a Cylinder 2 misfire. I'm thinking it's probably a bad coilpack. It could also be a bad ICU or even a bad EGT sensor. Any techs out there able to give me a definate? Also i'm still wondering how to fix this P1569 Cruise Control Switch ( E45 ): Implausible Signal. Thanks

use a voltameter and check if the o2 are bad or good.. it could be a bad spark plug or power coil
