Hey everyone... I kinda need your help. Once in a while, the idle does drop down to about 400 rpm but jumps back to normal. Today, I was waiting for a red light and the car just suddenly dies out. I tries starting it and it did crank but didnt start. I waited for about 2 mins and tries again and the car started. This happened 3 times today and I was checking the car and I see the oxygen sensor kinda worn. Do you guys think it is the oxygen sensor? Will the car run without or with a broken oxygen sensor? Because the car drives normally, well usually. Thanks for the help, I appreciate it.

You should check the Igniter and Coil.
Also see if there is any CEL (check engine light)
