    Brake switch question

    I have a 92 GMC that I want to use the brake switch from but it appears to be different from the one in the 91 Chevy. Did GM change the brake switch configuration from 91 to 92? I want to replace the brake switch with the one from the 92.

    Engine running poorly

    It ran very bad before a full tuneup but now it runs better but it does not idle. Also it sounds like its spitting (sometimes) when the gas pedal is pressed. If you let off the gas pedal it will sputter and die. Fuel pump/tank/filter is brand new as well as all 8 spark plugs/wires/cap/rotor
