Default 105K - 1997 GT, CEL w/ no symptoms...?

Howdy folks,
My 1997 GT has been near problem free since I've owned it, and hopefully this will be a sensor as opposed to a problem. It through a CEL last week on the way to the mountains and the lights has been turning off, and then back on, intermittently since then.

Any ideas?

Thanks,
Brendan

Any idea where you live? Lots of us don't mind pulling codes for fellow Subaru owners.

stop by a local autozone and ask them to scan the code for you - think they do it for free.

I got a code pulled a few weeks ago free by Auto Zone/Schucks. I think Pep Boys does it for free also. Just ask at the counter to borrow their OBDII scanner.

My guess is the O2 sensor if you're not feeling a difference in driving behavior. I had an O2 wire corrode and give me that type of CEL. Are you on the original sensors?

Pull the code and know for sure, it'll save you some headaches.

nah, I'll take the blame...it was after about 25 hours of continuous driving from AZ up to WA...I was a bit out of it and neglected to tighten it as much as I should have.

To the original poster... Mine has been doing the same thing for a while, the code always is miss fire in **random cylinder**. I've noticed it does this as my drivetran is shocked from decel to accel or vice vice. This is a known limitation of knock sensors of not being able to tell an engine knock from drivetrain shock.

For me I just chalk it up to transmission loosness/wear.

Yes I've replaced my plugs and wires

Thanks for the replies, been a few days since I had time to check here. I still haven't had time to mess with the car either but will this weekend. My tranny feels like the most probable cause, as it's a bit worn, but I need to go ahead and pull the code. I'm in NC - Chapel Hill area.

Any autozone or advance auto parts should pull the code for you for free.

My experience this weekend was:

Autozone: came outside and scanned the car with a scanner that displays the code directly, then printed it out in-store. They didn't clear the code and I didn't think to ask.

AAP: gave me a scanner and said 'follow the prompts and bring it back'. I scanned the car (it didn't display the code) then cleared the code out. When I brought it back inside they plugged it in and printed the code.

My GT is throwing a P0325 (Knock Sensor 1 Circuit Malfunction) code at the moment, which I'm going to hopefully look at this week. After I cleared it, it took ~100miles to come back so hopefully it's just a bad connection in the circuit.

lag - you can reposition the knock sensor to avoid the excessive vibrations as being interpreted as engine knock. Too much will retard your timing...
