Just bought this 06 ss/sc with 76000 on it two weekes ago. Check engine light came on with codes p0443,p0036,p0102,p0030 and the 10a emissions fuse was blown put a new fuse in cleared codes and blew again . Ive looked for bare wires on the 02 sensors and didnt see any. Could it be a bad cat?

Cat won't blow a fuse it has no electrical connection. Which fuse exactly is it blowing? Did you means the EXH fuse?

Sorry, same fuse they just changed the name in 07.

Disconnect both HO² connectors and install a new fuse and try to see if it blows again. You might have a shorted heater in one of the sensors. Then plug them one at a time to see which one blows the fuse.
