Default Very Predictable CEL

I recently started having a problem with a CEL that only comes on after I take the car to 60 mph or over. (I experience no power loss and i have a smooth idle). I got the code checked at autozone and they said it was a front O2 sensor (didn't ever get the exact code # though). Oddly, after about 2 days, or about 4 engine starts and cooldowns, the light disappears until i get back on the interstate above 60.

The service dept at the dealer said it is probably a bad cat...but it costs me 65 bucks just to have them officially check it. The service dept. guy (not a mechanic) basically told me to come back when the light stays on continously...

It sounds like the guy is correct to me with my limited knowledge. Sooo.....Is my car going to explode tomorrow? Has anyone else had this happen to them?

Is the car not fully warmed up? I find with my MY01 RS that if I keep the revs for a longer period of time between 2500-3500rpm when the engine is not fully warm it throws a CEL and then it goes away after 4 or five starts. Sounds to me like we have a similar problem

Why would the cat be bad if the 02 sensor in front of the cat be registering a problem?

Seems to me that somethings fishy. I would suspect a bad 02 sensor.

If there was a problem with the cat, you'd be getting a rear 02 sensor inefficency CEL.

John, your problem is definately similar, not exactly the same, i've had the car less than fully warmed up before and not had a problem as long as i stay below 60 mph... possibly is a bad/almost bad front 02 sensor, like blkts02 said. Anyone else have anything like this happen? Any and all input is appreciated from all you subie gurus out there

Rally shark, You might want to dig a little deeper on this topic. I believe there was some type of recall on the o2 sensors for our year rs's. Call the dealer and ask them.

Did you get the exact code #? Next time it comes on, have someone in your region (or Autozone) pull the code for you, this may help. Aside from that, it probably is a failing O2 sensor. I had my light come on periodically for about 2 months before I had any major problems. At that point, it got so bad that I couldn't even drive the car safely, so I had it replaced. It cost me $200, but at least I my car is back to normal and I've been CEL free for over a month now... Oh and one more thing; I developed a hesitation at highway speeds during the 2 months I had the reoccuring light, and that went away as well once I had a new one installed. Good luck, and once the light goes steady, make sure you have it replaced asap so you don't end up like I did!

cel at highway cruise is usually an egr problem or a cat efficiency code.

We can guess all day.

Try and get the code number next time it comes on, it will help immensly.

also register at www.my.subaru.com , you can find out any open recalls/camaigns on your car.

there was a campain on the 00 RS for the front 02 sensor.

rallyshark, do you have an AutoZone where you live. They pull codes for free. Get them to scan it and post up the code.

Thanks for everyone's help and responses. I'll go get the code pulled tomorrow, errr, later today, so we can figure out what's really going on

you probably do need a new sensor, is the date on there when it was replaced. It should carry a 1 year 12,000 mile warranty.

It was replaced under warranty already in 2001...so it appears warranty won't cover the o2 sensor. I'm at 53K miles and it was replaced at 24k...Oh well, time to spend MORE money at the dealer. Wish i had a garage to do all this work and not have to pay the dealer for all that expensive labor i love my GC8 RS, but all these glitches are bleeding me of my hard earned cash. Are the newer subies better as far as not having annoying glitches like these?

Peaty's was a 99RS and the 2000 RS o2 sensor is way different then that one. I would not use as a refference for that reason as you confuse some people.
