Default P0130 for o2 went away, but is now on again

My CEL was on for a P0130 (Front o2 Sensor Circuit Malfunction) for the longest time. I just replaced the front o2 sensor with a new one from the dealer less than 2 weeks ago. I cleared the codes after the installation and my CEL has been off since then until yesterday it came back on. Read it and got a P0130. What the ****! Any ideas? By the way, I do have a leak in my exhaust but it's after the cat so I don't see why it would be the cause. HELP!

Same problem on my 2000 forester L. I'm thinking about dropping some money for an exhaust system

My b.. Hit send by mistake. Anyway, since I wanted to replace the I original exhaust system with a custom performance system. I can't help but feel that now is the time to start the upgrade since my original one now is broken. Except I'm new to subarus' and don't know if it'd be a good idea to upgrade.. Help please?!?!

Sorry accident.. I wanted to upgrade my current exhaust system to a custom performance system, and now since my CEL code is a P0130 I feel like now would be the time to upgrade.. Can some one please steer me in the right direction.

Getting an exhaust will not fix your problem...

Default Good luck

I am currently experiencing the same problem with an 03 Impreza. I replaced the sensor once, code came back. I tried rewiring the 02 sensor connector directly back to the ECM and the main relay which then changed the code to a p0030 and p0031. I then returned all wiring back to stock and replaced the sensor again and the p0130 code came right back, I am now currently stumped beyond belief.
