Default Code P1399 Anybody?

So I'm pulling into my driveway last night and the check engine light comes on. Car is still running fine and everything so i head to the garage and get the trusty Actron code scanner. I don't remember the first 3 codes exactly but it's close and i remember what the descriptions are.

P3020 - Cyl 2 misfire
P3030 - Cyl 3 misfire
P3003 - Random/Multiple misfire
P1399 - Manufacturer Specific

"Ok" I think, lets bust out the Helm's manual.
To my dismay of course the code is not in there.

Google search: Chrysler light switch code or something to that effect. Search: a bunch of stabs in the dark but nothing solid that i could find.

Didn't really have time to mess with it last night so i just cleared the codes on it and drove it to work today (only mode of transportation). I was easy on it but the codes didn't reappear and it drove fine as far as i can tell.

So first question is, anyone know what this code really is?

Second, what's wrong with my car.. bent valves, plugs, rotor button, cap wires, just an odd coincidence, valves out of adjustment, loose nut behind the wheel?

I'll be doing a compression test tomorrow as well as possibly ordering some tune up parts just to be safe.

Are you positive that it's not a P1359?

The scan tool indicates Diagnostic Trouble Code (DTC) P1359: A problem in the Crankshaft Position/Top Dead Center/Cylinder Position (CKP/TDC/CYP) Sensor circuit.

I'm positive that i wrote down a P1399 but i guess it's possible i copied it down wrong or sloppy. From searching H-t there were several threads with people asking about this code but with no real responses.

None of the codes you listed are valid codes per Honda.
