Does anybody know if the 1995 Bonnevilles are ODB-II compliant? Mine seems to have the correct connector, but I've heard that the computer wasn't compliant until 1996. Has anybody tried using a Tech2 or an AutoTap on their '95?

I believe that is correct. It'* the same years as the grand prix'* I believe, so it has to be like 96-97 and up.

odb1 baby!

I am seriously considering a scan tool for my '95 SSEi (series 1 SC). Looking at a few scan tool sites:

http://www.obd2.com/personal/personal_gmobdi.htm

http://www.autotap.com/faq.html

they show the OBD 1 + 2 connectors. The connection I found (under the dash at the drivers knees) is exactly like the OBD 2 and not the OBD 1. Does this mean I have an OBD 2 connection or do I have just the plug and do I still get the OBD 1 tool? If I get an OBD 1 tool, will the connectors fit together? :?

I just want to make sure I get the right one since I hear that the OBD 2 didn't come into play until '96.

I am also wondering how much information I will be able to pull from this. Will it tell me if a cylinder is missfiring, timings off, various sensors gone bad, or ....?

jeff, try using a Tech II with either a Tech I adapter or Tech II adapter. I do believe it'* still OBD I though.

You hit the nail on the head. Found the label and it is an OBD 1 PCM with a OBD 2 connector. Just gotta find the right tool for it now.

Any suggestions???

jr's3800,

Where did you get your scan tool? I've been looking for one, but don't want to spend a whole lot of money. Thanks for your help.

look on e-bay.
