Default Engine Code, Need Help

I own a 2003 PT Cruiser and the egine light is comeing on. The symptoms are that the engine runs really rough at sporatic times. It has huge decrease in power and spudders and almost stalls at some times and other times its completely fine. I hooked it up to a OBD II sensor and the codes are P1681 and P2302. I replaced the coil, spark plugs and plug wires and still no change. It still has the engine light on and still runs the same.

The first question is on P2302. This is the ignition malfunction. What else could it be besides what I already changed?

The second question is what is P1681? It seems its a dealer code and I cant figure out what it is.

Any help would be great
