car stalls and crazy light comes on
Assuming the “crazy light” is the same as the check engine light, when the van stalls there should be a code stored in the computer. Have the code scanned (Auto Zone will do it for free) and report back with the code. It would also help to know the circumstances when it stalls, i.e., pulling away from a light, turning, climbing a hill, etc.
The Check Engine will always come on when an engine stalls, so there may not be a stored error code.
Under what conditions does the engine stall?
You mean this light that drives people crazy, except the professional technicians?
