    OBD connector w/loose contacts?

    So I'm in my car ('04 WRX wagon) with the key turned to the 'ON' position and I'm trying to do some testing with various OBD scan tools. I notice that I'm not really getting the steady responses from the scan tools that I should be getting, so I go though my normal routine of checking cables and connections.

    I notice that when I jiggle the OBD cable/connector the scan tool will reset itself. If I apply light upward pressure to the connector, I can get what appears to be a "solid" connection and the scan tool acts as expected.

    I'm testing these scan tools for work and they're all very basic interfaces (~$100 apiece). So just for kicks I hook up my AccessPort. As I jiggle the vehicle connector on the Cobb cable, the AP will sometimes reset itself as if it's losing power for an instant.

    I know Cobb's instructions explicitly state not to bump the cable during reflashing and I've used the AP for a couple reflashes without incident, but all this has gotten me slightly concerned.

    I've been considering going open-source with my EM, but I'd like to avoid any unnecessary reflashing if I've got a wonky connector.

    Does this sound like normal OBD connector behavior? If not, has anyone ever replaced the OBD connector in their car?

    I remember hearing cases of people having to "wiggle" them to get them to work so I'd call it "normal".
