Default AVCS questions and missfires

Is there supposed to be a difference in degrees between left and right on start up? At idle avcs in left reads 22 to 25 degrees and avcs in right reads 7 degrees. My car idles rough on start up and throws missfire codes on all 4 cylinders along with PFFE . No issue's otherwise. The car is definitely not missfiring all the time. I did change from a dual mass flywheel to a singlemass stock flywheel. that was close to 30k miles ago and the codes didn't start until a few weeks ago. Any ideas? Its a 06 forester xt by the way.
