Brian filled in the info about OBD1 & 2 systems. I have a laptop package for OBD2, and you can really learn a lot about how things work by watching a bunch of different functions graph at the same time.
 
The newer cars have O2 sensors with multi wires because they incorporate quick warmup heaters and other functions. The older cars were often just 2 wire. The parts counter will give you the correct one for your year.
 
My suggestion about removing the cat was only to help diagnose if the present one was clogged to the point that it was restricting flow & causing driveability issues. If not, put it back on. If it is, replace it. I value the air we breath very much, and do not advocate permanent removal the cat.

Hello Linda. My wife and I also have a 96 outback and we are experiencing the same issues. We also had plugs and wires replaced and it addition had Oxygen Sensors replaced and we still have the same issues...Car stalls when cold and going up hills...Loss of power followed by engine shut down. If you've had any luck lately please pass on the advice.

#5911 of 8644 Check engine light by markk1

Mar 06, 2006 (10:32 am)

My 2000 Outback 82K has had the check engine light go and off for the last month or so. It seems to come on for a day or two and then go off for a week or so, probably done this about 3 times. It turned out coincidently I had a dealer visit just after the first time. The dealer told me not to worry about it since it turned off. I should note that I have been carefully checking the gas cap so that is not the issue and my car passed the emissions inspection when it was at the dealer.
 
Any thoughts? should I be concerned about this?

If you decide to 'lose the tires' and go so far as to get different wheels...let me know. I am looking for a set of GT wheels to put on my 01 LL Bean outback.

Have you tried replacing the mass airflow sensor? My '96 was having a stalling issue when I first purchased it back in Aug '00, and while I (nor 4 different dealers and/or mechanics) was never able to diagnose the problem definitively, the last mechanic suggested that I *try* the MAS. I purchased a used unit and had it shipped up from Seattle. I have never had a stall since..... ?
 
Oddly, while the CEL would illuminate each time it stalled, no code was recorded. Maybe I just got lucky.

You could go to a dealer or just about any decent mechanic shop and get them to plug in a scanner. Even if the light has gone out the record stays in the computer for a while afterwards.

Some suggest rolling into the throttle gradually. See if that helps.

Hard failures trigger the light and it will stay on forever. Soft, or intermittant failures trigger the light, but if they do not reoccur for 3 complete driving cycles (cold start, full warmup, certain distance driven), the light will go off on the fourth startup. However, the code remains in memory for, I believe, 40 full cycles. In addition to the diagnostic code being logged, the 'readiness indicator' will not be set. So if your state requires that the computer be read out to show OBD2 compliance, you will fail the test.
 
Did you get a slight stumble when the light went on? When I had the same symptoms as you, it was an underperforming front oxygen sensor.
 
You need to get it read and find out what is up. Autozone and some other retailers will do this for free.

Coincidently the day after the light went off the first time I had a NYS emissions inspection at the dealer. I was told when I made the appointment that if the check engine light was on I could not pass the test that day (even if they fixed the problem). When i got to the dealer the light had turned off by itself and they were able to inspect it. No change in performance that i can tell when the light goes on.

will give it a try, anyone notice any better transmission shift learning using the "sport" position?
