How long does it take for the computer to reset

You can either reset / erase the code after replacing the oxygen sensor or go through a few "drive cycles" and it will reset itself. Can't remember off the top of my head how the cycles are defined. Alternatively get your hands on an OBDII reader and reset the code.

My 01 Subaru forester 2.0 is misfiring and smells really rich. It happens at idle and is really bad under load and at lower revs. It gets better but doesn't go away when the car warms up.

Sounds like you need to replace the oxygen senors. They control the fuel and the timing. The sensors tell the computer weather the engine is to rich or to lean on fuel. I hope this helps you fix your problem.

I hope you didn't change the O2 Sensors based on a code.
OBD2 Systems don't work that way. The codes only point to an area of the powertrain with an issue. I also hope you tested the sensors first, otherwise you were installing parts, that were most likely okey.

Is the Air Filter clean?
Have you cleaned the MAF Sensor ---CRC MAF Cleaner?
Have you cleaned the Throttle Plate---CRC Throttle Body Cleaner?
How old are the spark plugs---More than three years or 50,000,get rid of them?
Are there ANY Leaks in the ducting to throttle or any hoses leaking---most common cause of O2 Sensor out of range and code set (MIL Lamp On)
Do you have PO300 Codes?---COP Coils Missing,All Fords have one or a year go bad.
If you have the original EGR Valve--throw that away,and get new one. Should have failed before now.
Coolant Temp Sensor ! Not working correctly would keep taking it out of closed loop and affect O2 Senors
TPS Sensor--worn and be your only issues. Two Torx screws to remove and avail on line or parts store ( do yourself) ONLY after testing and only if tests bad

Check engine light is on

Typically most vehicles will have to oxygen sensors. The job of the oxygen sensor is to measure the oxygen going into the intake and measure the oxygen from the exhaust. This will tell the computer how well or bad the vehicle is burning your fuel and hence adjust fuel level and other components to keep your vehicle running well. If the computer gave an faulty oxygen sensor, it may be clogged and need replacing. Typically oxygen senors are inexpensive, but due to the location of some of them, troublesome to replace. There is also a special tool you will need, looks like a socket, if you are going to be working in a tight spot. Hope this help you out.

Location of oxygen sensor

All of your oxygen senors are located in your exhaust system they are 4 of them on this vehicle. They are all screwed in to exhaust pipes with wire connections on them. All that's needed to replace them is an oxygen sensor socket and a ratchet this can be bought at any auto parts store. Good luck and thanks for using FIX YA
