2003 trailblazer 4.2l throttle pedal
 

After 2 months of looking for a gremlin finally found it. This even fooled a expert and they could not find the problem. ABS lights, brake light, driver1, and unknown driver, air bag lights and seat belt lights on and off all the time. Turn's out it was the switch on the acelerator pedal grounding wire with bad connection. Replaced the pedal with new switch and that took care of the problems. Took a butt cutting on this one I would say.
