    Weird! Did you turn them off?

    Sounds like something might be shorted out somewhere. Not sure why that would cause a CEL. Where did you make your electrical and vacuum connections for the boost gauge?

    If you or someone you know has access to an OBD-ii scanner, it'd be a good idea to get things checked out just so you can clear the code and figure out what it was.

    On top of the steering column is a switch. I works your parking lights, when I get my car washed they always hit it and it was confusing at first.

    Hopefully thats all it is,

    me too. it's a pkg lite switch (rocker type) for when the car is off.

    Unhappy uh oh!!!

    well i fixed the lights but when i went to drive my car the check engine light was flashing, im not sure if it always did this but the fan would go on and then cut and then on again,and it was also making clicking noises alot.im not sure how could i have caused this just by moving the gauge to a little bit. also the rpm's would slightly go up and down while im idling,could this be my bov??
    i took it down the street just to see how itd run,and itd make a wierd sound when i braked

    Please anyone who knows why my car might be acting so strange,im not to sure about taking it to the dealership cause they might not help me out.

    if someone could give me some reasons why my car might be doing this please help me, i want my car back to normal,or if anyone knows how to fix this problem,i hope its not too serious ...could someone get back to me asap!!! thanks

    PRS,

    It sounds like your car is in "sensor cycling" mode. This is a setting for technicians to use in order to be able to walk around the car and verify that all of the sensors and switches are working properly. This mode will also cause the idle fluctuate so the technician can observe the engine's response. There are several connectors just below the steering column (black, green, clear/white). Two of these connectors plug together to engage this cycling mode. Disconnect these connectors using a small, flat head screw driver to disengage the plastic lock and the car should return to normal.

    Hope this is all that's wrong!

    Also, please don't double post. If you do by accident, inform a moderator via PM. Thanks.

    -Jim

    I gotta ask this. Why did something get plugged in that wasn't supposed to on a gauge install and why does Plat know this?

    Root,

    It looks like "plat" will no longer suffice as a nickname for me on the club. I put PRS for PlatRexSubie, so I guess PW would work for me, you could always put "Jim" when faced with this conundrum again.

    If you any of you are wondering how I knew this, the answer is, "Quite frankly, I know everything about the WRX!" Like all things that interest me, I attack each car that I purchase with the intent of LEARNING ABSOLUTELY EVERYTHING ABOUT IT. Why else would I be so involved in such a WRX-centric club on the internet?

    LOL I did this as well when working under the dash. (can't stand things to not be connected) I Freaked out when I turned on my car, but quickly realized what the problem was. Thanks for the explanation Platnium WRX! =)
