engine sometime dies at red light. All light flashing while engine starts & runs very smooth. I can hear clicking noise coming from radio lclock light & from door at head light switches. I have replaced egnition module , fuel pump, plugs, plugs wires & all but one relay under hood on fire wall. All lights flash on & off while motor starts & runs smooth. What's up? I have put it in one shop 3 times & another shop once. No one can tell me what's wrong.

Have you checked for vacuum leaks? Have you checked the idle air control valve?
