On my 85 FJ60 gas wagon the dash parking brake light is bright when the brake is set but when I release it the light stays on dimmly then when I rev it up it almost goes away with higher RPM. I recently moved the distributer for better idling and that is about the time the light showed up. I tried moving it back and it has no effect on the light. I also screwed the idle screw up a bit to help with the engine dieseling problem and the light is still on. I know this light is telling me something but cannot figure it out. Any thoughts?
