OBS II Question for '96 Buick PA

[steelman1958]

I have searched this forum and elsewhere on the INet but I have not found exactly the information I am looking for. I have a 1996 Buick Park Avenue that occasionally has the engine light pop on. I brought it into the dealership and they said I just needed a new gas cap since there was a bit of a vacuum problem (intermittent), and they reset it. I bought a new cap and the problem only appears once and while (which is less than occasionally). I purchased an OBD II module to check to see if the problem is still the same and so that I can reset the light. However, the instructions don't show where to plug in the module, and I can't find the information anywhere else. I would appreciate it if someone could tell me where to find the connector on my car.

Thanks.

Look under the dash on either side of the steering column.

Connecting the dots here and going on a hunch:

Trouble code says problem in evaporative emissions system accompanied by a vacuum leak, I'd be looking at the charcoal canister purge soleniod, it's a main part of the EVAP system and utlilizes vacuum

I found where the OBD 2 Reader connects to the PA. The plug is located under the dash, just above the brake pedal towards the steering column.

I received the code "EVAP Purge Solenoid Control Circuit". What exactly is that? How do I go about fixing / replacing it? Is this something that is fairly easy to do? I would appreciate any help this forum could provide.

Thanks.

Sorry, I missed the question on where the connector was.

The problem is either in the wiring, vacuum hose, or solenoid itself. Since it si intermittent, I would love to say it's the solenoind itself getting tired.
