Default Re: Just died 5 times at stop lights...

Is it dying while coming up to the stop light, or after idling at the stop light?

If it's while idling at the light:
Without doing any testing at all...I'd blame the crankshaft position sensor. Even after doing testing you're likely to need to replace it anyway, but then you'd be more sure of the money/time spent on it.

Try to get someone else to ride with you, or let it run/idle in the driveway until it dies with someone else around. Need them to turn the key to "start" while you have 2 adjacent spark plug wires pulled off the coil towers so you can check for spark.

If coming up to the light:
I'd blame a dirty throttle body and/or sticky IACV. Simple fix is to buy another throttle body gasket and some O2 sensor safe carb cleaner, take the throttle body off (being careful of the fragile vacuum lines on top of it), remove the IACV and hose down the TB including with the valve/flap opened so you can get that cleaned up too. Don't spray the IACV and be careful not to move the plunger location, moving it won't break it but will make restarting harder than necessary.
