I know my '95 had one issue (not sure if it was an actuall recall or some sort of service anouncement). There was an issue with the twilight sentianal (light switch) that caused the lights to go on or off at will.

I just happened that I found it searching the web. I went back to the dealer and they said that it was already changed out before I got the car, but who knows.

Default 02 sensor

I have never changed the 02 sensor on my 96 SE. After reading about the 30-40,000 miles change I called and they told me there are 2. One in the manifold somewhere and one after the catalytic converter. Is this true and if so do you have to change both or is 1 or the other more important than the other. The car seems to run basically fine, so I just never changed them out. Ideas?

Amy, sounds like you might be able to get your codes after all. The 1995 was OBd I compliant, but had the OBD II connector....I think. If Big T has the pins, this would be invaluable. Stay tuned for him, and then most of us have the manuals to decipher your codes. I'd do a visual inspect on everything else, but the PCM codes would be most revealing!

Dylansdad, I changed my O2 sensor (I only have 1) on the advice of JR's3800 (if memory serves me). I had 75,000 miles...just changed it 2 weekends ago. For me, it made a world of difference. If you're not having problems, the car is still getting the same basic mileage, and the exhaust doesn't smell rich (when the car is at operating temp), I wouldn't touch it. If it ain't broke, don't fix it As far as both of them go, I think it'* best to change them both, but you'd do better to hear this from someone else who actually has 2 in their car!

It would be great if I could check the codes that way, without the high-tech gizmos. All I know is that the terminal that is under the steering column is 16 prong. well, I'm not sure that is totally accurate...it has 16 spaces, but only 6 little metal things. Hopefully that doesn't make a difference.

6 little metal things......isn't that CUTE! Amy, we're going to be your ruination. You're gonna get greasy, dirty, and smelly, but your car is gonna look and run great!

BTW, You and Tam aren't the only female variety.....there'* a married couple somewhere around here, and I think she posts occasionally.

But you're still SERIOUSLY outnumbered, so don't get over-confident

Oooppps, made a slight mistake in a earlier post, The Bonnevilles actually were made with the ALDL 12 pin DLC up through a certain part of 94 so if you have the connector like Willwren is describing above, than you might be able to get the trouble codes out of you car with a code key or jumper wire,but there is a small chance that there will not be a diacnostic terminal present....if not then you need a scan tool.. These cars use 2 didget trouble codes.... now if you have a 94-95 OBD I with an OBD II connector( 16 Pin connector ) Than your car uses the 5 didget trouble codes like the 96-99 models. In other words, all 94 Bonnies with a 16 pin connector and all 95-99 are all OBD II compliant, Even though the 94'* and 95'* were OBD I certified....

Ahhhh, How Sweet.....Theres a lot of love here...

Ummm....here I go sounding like an uneducated female again *grin* but what? Okay, so I have the 16 pin connector (16 holes, right?) So do I or do I not have a diagnostic terminal? Wow I'm so confused...but I think I'm learning. Thanks for being patient with me everyone. I love learning about my car.

Here'* the bottom line, or at least part of it. You have a '95 SSE (I got a '95 SSEi) and that means you have a OBD1 PCM with an OBD2 connector (larger connector). Your PCM is almost OBD2 compliant but not quite. Although the connector is OBD2 that doesn't necisarily mean that the pins are in the right spot (others can maybe figure that out), but my guess is that if those with a OBD2 cant scan you (we) probably cant either since it is the same connection.

Don't feel bad about not getting this right away. Most of us still don't fully understand it. '95 was a transition year with the mix of OBD1 and OBD2 hardware.

I hope this helps to answer your question.
