Codes P0703 and P2299 are stoplight switch codes , but when stoplight switch goes bad it can knock out electric throttle when driving .  Does not have to be on cruise , or at high speed . Computor senses throttle is applied and then that brakes are applied and knocks out electric throttle . Sometimes just a little movement of throttle pedal will wake throttle back up . Another clue is a red light in cluster with the symbol   ) / (  [ slash is electric volt ] will come on when problem occurs . This problem with knocking out throttle will not occur if brake is applied - then throttle [ as in power braking to load an engine ] .  This p[robley should also be posted in brake section .     Butch
