Misfire and Camshaft sensor (R55 N14)
 

Just bought my 09 MCS Clubman, 64k miles, carbon cleaned and timing chain replace before I bought it.

The other day driving at highway the CEL comes on and the car is running really rough. Stopped at the local AutoZone and had P0340 Camshaft Position Sensor Malfunction and P0304 Cylinder 4 Misfire. I checked the Coil by switching it with Cylinder 1, and then I got the codes that all other Cylinders are misfiring. I bought the socket to check the plugs, and I'm waiting for that to come in.

My guess is that the Camshaft Sensor failed, and needs replacement (which is easy), I just want to check the plugs before I order it. Just checking here for any other possibilities. If fixed, i'll let people here know.

Also, anyone in the San Antonio/ Austin area that could clear my codes?
