So I was at a red light after getting off from the freeway , as I was waiting I notice my car shut off on its own and all the lights came on , oil, battery ect... put on my emergency light and pop the hood , I look around and notice that one of my spark plug wire pop out from the distributor cap, plug it back in but car wont start any more, car cranks fine but wont start, what could it be ? I am a complete noob to this ,

PLEASE HELP THIS NOOB , NEED TO FIX ASAP SO I CAN GET TO WORK.

Thanks

 

Should I just replace the distributor cap and rotor and spark plugs?
