Hi everybody,
I was driving home and suddenly my CEL came up. Drove to a close AutoZone and the scanned the code.
That's what i got from them :
P013F - lean to rich bank 1 sensor 2, O2 Sensor had delayed response - lean to rich predetermined period of time.
what does this mean ? i'm new to the whole car scene and kind clueless about it and couldn't find anything at the forum with this code/solution.
I Just put Nameless Axlebacks on the car, could it cause the problem ?
Thanks In Advance!

What modifications do you have if any besides the axle back

Call them and have them flatbed the car to their service department. Have them provide you a loaner car. All this of course is built on the assumption that you did not inadvertently damage the wiring to any sensor when replacing the exhaust.

What wiring ? i just removed my mufferls, there was no wiring included in it.
It is the Nameless Axleback Muffler delete.

Brilliant. You have zero problems. This is the dealer's problem.

We had exactly the same problem with our Forester on a long trip in rural Wyoming far from home (and tools). The car ran fine otherwise so we continued on. A little research when we got home suggested:

EVAP System Leak Detected Very Small Leak
Possible causes
Missing or loose fuel cap
Incorrect fuel filler cap used
Fuel filler cap remains open or fails to close
Foreign matter caught in fuel filler cap
Evaporative Emission (EVAP) canister or fuel tank leaks
Evaporative Emission (EVAP) system hose leaking
Fuel tank leaking

I carefully cleaned the fuel cap and gasket and the fuel filler neck with a clean cloth and isopropyl alcohol. The problem disappeared and has never come back.

Thanks for the advice although it wasn't the problem.
I took the the car to the dealership and got it fixed in a giffy.
they replaced an o2 sensor that went bad !
