CEL codesd read - misfire detected

My engine slightly stumbled on takeoff briefly, and the CEL came on... a couple weeks ago. So, I ordered the Durametric, and read the following codes:

P1319 Unknown DTC
P1317 Unknown DTC
P0300 Porsche fault code 507 Misfire detection
P0305 Porsche fault code 513 Misfire cylinder 5

So, Hopefully I have a simple plug or coil pack issue. This happened the one time in 105degF temp under otherwise normal driving conditions. WTF is an "unknown DTC"? I don't like it when a $300 tool tells me "unknown"

...and would you guys suspect a coil pack as well? ...or even something else?

Thanks, Chris

Knowing I had a misfire on cyl 5, I decided to swap coil packs with cyl 6. It threw a code the next day convicting coil pack on cyl 6. Yay me!

Any recommendations where to buy a coil pack?
