Sea foam. Oil changes at 3K miles.. its well maintained.. I dont granny shift i shift usually around 5K rpm..

Could be carbon, but if both codes happened at the same time (was the check engine light off before this problem happened?) it's most likely a wiring problem, or a PCM malfunction IMO. The former is more likely, and will be hard to diagnose... the latter will be expensive. If you don't know your way around a volt meter and a wiring diagram, take it to a shop that knows a bit about RX8s or a dealership that you trust and have them look at it.

Also, are you certain about code P0039? That code isn't even mentioned in the service manual
