06 questions

I was just wondering if the 06 models have wire chafing problems. My ficm checks out good at 48.3 on cold start. But i am still getting cylinder contribution codes on cylinder 5 and 6. It only throws these codes on first start up when temps are below 30. If i clear them out they will not come back until the next morning. Just curious if it is a wiring problem or injectors need replacing.

Sounds like injectors. If you aren't already running a 5w-40 synthetic, switch to that and it will probably help a lot.
