I've got a 92 Toyota 4x4 pickup that has anti-lock brakes and the ABS brake light stays on all the time now. In the morning when I first start the truck to go to work, the brake light ( the one for the parking brake) stays on for a while as well, but it'll go out. I have a feeling that the normal brake light comes on because the computer knows the ABS brake light is on. My brakes feel normal when being used and I'm wondering what I need to do to fix the ABS brake light issue. My Toyota manual doesn't say very much about ABS troubleshooting.

Also, how is the throttle cable supposed to be adjusted after you've taken the intake off? My manual does not say anything about the adjustment of the throttle cable either. I noticed that there is a arm on the throttle linkage that touches a round dowel looking thing that has a flat tip screw driver head ( this would be on the side toward the front of the engine. I've noticed that I can manually move the throttle linkage just a little bit before it actually starts moving the throttle plate. I don't know if that arm piece is supposed to rest against that dowel looking pin part of the tbi either

Thanks for the help,
Doug
