You might want to take it to a dealer and have them run a diagnostic. You don't have to have them fix it but you will pay somewhere in the neighborhood of 70 -100 bucks. I know the crank sensor isn't the fix all to every problem but if it is mis-firing it may just be the crank sensor which costs around $20.
