2005 Subaru Baja Question: Check Engine Light blinking

My check engine light went on and I took it to subaru to see what it was. They said O2 sensor. I fixed it and a week later check engine light back on. Brought it back and I was told it needed a tuneup, now tuneup didn't fix it. Car idles rough, hesitates, and check engine light is blinking. Any ideas? -
Answer 1
wires and coil may have to be replaced as well. i do that as part of a tune up Roy -
Answer 2
Go to an auto parts store and borrow their code reader so you can get the specific code it's throwing and report it back here. That will help with diagnosis. -
