Tracking down Fault codes

[Aanic]

Team,

I need some help on some fault code issues. Recently I had some serious misfires on the 99 Boxster. It was misfiring so badly that it would barely run. I replaced all the plugs and coils, and now it runs great, but I have a CEL on with the following codes:

P0102
P0112
P0154
P0302
P1318

I know several of these indicate misfires, which I believe may be holdovers, but with the two MAF codes and the Oxy sensor code I'm wondering if there is a common thread, or if they also could be holdovers.

Timeline: Within last 100 miles - new coils, filled up with gas, misfiring gone, but CEL on.

Thanks in advance,

Aaron
