Default 97 Outback - Need Help!

I bought a 97 outback about 2 months ago and it was driving awesome until this week. It started by running really terrible at a red light while stopped in drive. It seemed to only give me problems while stopped at an idle, but more recently it's been having terrible power loss until about 3000rpm and having a poor idle some of the time. I replaced the o2 sensor but it's still running very poor. Over the length of this week it went from driving perfect to almost unable to run. Any suggestions?

I suggest you check for codes......it must have some if it's running that bad.

it had the check engine light on when I bought it, p035 for knock sensor, but that was when it was running fine. I need to scan it again, just dont own a scanner. only paid $1000 for the car

That was my next guess. I was thinking about dropping the whole exhaust tomorrow. I did just run some seafoam through the tank and in with my oil, that's what made me think something gummed up my o2 sensor. It happed the next full tank after the seafoam.

is the check engine light on or flashing? if its on check for codes and if its flashing then most likely its misfiring.

Solved! Previous work was done on the harness that plugs into the MAF sensor. Looked pretty ****ty so I cut it out and put on some new wire runs like a champ once again. Better than before, no more engine light since I changed out that knock sensor.
