Welcome to AF.

Your post has been moved to it's own thread. We prefer that posts concerning Regal models after '97 are not shared with earlier models prior to '97.

A common problem for unexplained stalling may be the crank position sensor (CKPS) if the fuel pressure is within specs. A fouled spark plug will typically cause a misfire condition not stalling. Normally the SES/CEL light will blink or illuminate and a DTC code may be stored. On CKPS problems the SES/CEL light may not turn on.
