My van won't stop stalling out. It used to run perfect until I got the timing belt changed. What could be wrong?

Well, to start with... this isn't autozone.

But I'd recommend taking back to the people that did the job. Because they did it wrong. Likely the timing is off.

Smoothy is right. If it was OK before and you had someone work on it, then take it back to them.
