I have a 1994 ford explorer and it keeps randomly stalling what is it?

Already put new fuel pump fuel filter crank sensor and bypassed the inertia swich i don't know what else to do.

Any codes? Take it to a national auto parts place and have them run a free scan.

Idle air control valve? You know it would have been cheaper to have the vehicle diagnosed and repaired right the first time don't you?!
