Oops. Sorry about the lack of information. 2009 Legacy GT 5spd manual just tripped 160K during all this crap. I had taken to the dealer until recently. The work had severely degraded so I refused to go back to them. O2 sensor is Subaru, they had used some aftermarket but changed it, but didn't matter.

I'll try to make this short. End of January - CEL - misfire cylinder 4 Coil pack and plug replaced Mid Feb - CEL - misfire cylinder 4 Before I get to mechanic CEL starts flashing, sounds horrible was 1 mile from shop No compression, ends up having a burnt valve, engine pulled, heads redone, also found some other issues with cam phasers, replaced O2 sensor, got back together and continue to receive CEL Misfire cylinder 1 for mechanics before returning car to me, reset I got car back, misfire cylinder 1 - replaced coil pack and plug one this and 2, 3 cylinder so now all are new I get car - CEL misfire 3 & 4 return to mechanic, not sure what they did, received CEL again, return they drive for a week without issues, I get back and light comes on almost instantly for me, this time cylinder 1 & 3. One of the 3 & 4 misfired smelled of raw fuel, O2 reading .86-.90 volts I suggested replacing fuel injectors but with misfire moving, I'm stumped. Any ideas? I want my car fixed and back, this has been ongoing for 3 months. It could be I'm jinxed too... Borrowed a couple cars and tensioner /serpentine belt broke on me, got fixed and then water pump went on me. The other car I borrowed got a flat tire because TPMS sensor broke on me and it's part of valve stem. Now my truck's CEL comes on with 1/4 tank fuel left. I'm so over vehicle issues...ugh.
