    What year grand prix has a 3100?

    I thought they were introduced in 97 or something? I'm looking at a 95 with one... Is it an engine swap or am I crazy?

    Also, OBDII? Any way to pull the codes easily?

    3100s were introduced in almost all cars in 94, so a 95 GP should have one. Yes, it will be OBD2, and no, no easy way to pull codes. GM removed the option to pull codes without a scanner when they went to OBD1.5, and have been that way since...

        Em no it won't be OBD-II, unless it's 96 or later.

          I thought 96 was just the deadline for all cars to be obd II and some got it a few years earlier. I've used the GM obd II scanner for my 94 2.0 with a connector adapter. Maybe thats the obd 1.5 bszopi was talking about.

            Oops, I mispoke... Was thinking 96, not 95. So yeah, it'll be OBD1.5, not OBD2.

                Went to advance, and they pulled out their scanner, but it wouldn't fit the OBDI connector.

                So I have a couple questions about that.........

                "OBD 1.5" is an OBDII computer with an OBDI connector, correct? Are the codes pulled going to be OBDI style - like "code 32- EGR" or OBDII style - like "Code P0234 misfire cylinder 2"??

                Second, I already have an ALDL interface. The nearest autozone is 6 miles away. Is there any software I can use to scan the codes myself?
                Okay now, that's enough of that.
