1997 gmc 1500 xcab reverse lights come on when braking

Sounds like someone put the bulbs back in the wrong holes in the taillight. Or two wires are shorting together. Either way , I think if you remove the taillights , you will find the problem easily.

Check fuses first. If thats OK, could be a problem with the brake switch (down by the pedal) or the wiring.

1985 GMc sierra boggs out at idle

Sounds to me that the carb. is bad, most likely its a Qjet, best thing to do here is to have it rebuilt, but better yet get a replacement, unless you know someone that will rebuild it for you witch i dought, they don't call them Qjunk for nothing.
