P0330 Knock Sensor
Good afternoon All,
I recently bought a 2013 C06 with 15000 miles on it on Craigslist.
The guy who sold me did not tell me there is check engine light. and when I started driving I noticed check engine light
and I checked with my OBD reader and it is showing the following codes
1. P0330 Knock sensor Bank 2 Circuit 2
when I am driving over 90 I feel I have to accelerate too much to get to 90+ speed.
2) P0449 evaporative leak.
3) Horn not working.
Just wondering if anybody has similar issues and what they ended up doing.
Thanks
sam

P0449 may be triggering the P0330. 
Info on P0330 seems to say the code can be attributed to several different sources.
Evap leak, cooling system, bad knock sensor, ks harness or bad ECM.
Evap solenoid failures are common, FWIW mine went south at 50K on my '08 Z06.
A skilled tech must follow a specified procedure (on WWW) using a Tech II to isolate what's behind issue.
Horn may be as simple as bad switch.

You have an OBD reader and didn't bother to check the car with it before purchase?? just checking.
ALWAYS check OBD before buying a car. Common problem with that is seller may disconnect battery and clear codes before selling. May claim battery went dead while sitting. In that case your OBD reader needs to be a more sophisticated OBD scan tool that will display I/M monitor readiness. This will indicate if car has gone through enough drive cycles to demonstrate that it will pass an emission inspection and codes are not trying to be concealed.
P0449 evap vent solenoid - fairly common issue - about $20 with correct harness. At right rear wheel well. Not to be confused with evap purge solenoid.
