The one about check engine light.

 

Ouch - that is a nasty list of codes/problems.

I'd suspect that the exhaust leak (if upstream of the O2 Sensors) might be causing a few of the problems (p0106/p0300/p0327). If it was me, I'd get the exhaust problem fixed then see what else improves.

We also need to know what engine you have: 2.2 or 2.4L? there are major differences between them.
