  1. 09 Legacy GT: CEL and P0304 So about a month ago (shortly after replacing US and DS 02 sensors and battery) my CEL started showing up again, this time with P0304 code. Replaced plug and coil on Cyl4, CEL came back after about 100 miles, checked injector and found it to be "ok". Back at the dealership and now being told that it has to be an internal problem (bent valve, cracked piston, burnt ring, etc..) however all compression tests and other diagnostic things come back clean. So I'm told I have a "terminal" problem... at just under 130k (this being my 4th Subi, and the first to not cross the 200k mark) I find that hard to believe. *Swapped injector and coil and the problem stayed on Cyl4. So here I am looking to the brain trust here to throw some ideas my way to see if I can figure out the mystery of the P0304 on my LGT. Any ideas? Thanks in advance.
