My wife's [ Mary Pat] 94 Buick Regal keeps stalling while going down the road....sometimes as much as 10 stalls on one trip from Lower Gwennyd PA to Holland PA.
Her car was in O'Neill's Buick in Warminster, PA for a week, & they could not solve the situation. It was slso in Kar Klinic of Southampton , PA for 3 days & they found nothing while on their dianostic machine.
This is a VERY dangerous car.

Considering car hasn't been used for over a week...
Runs great for differing lengths of time. When the problem occurs, the engine develops a miss, and anytime the throttle is depressed (at any angle) the engine stutters and dies. When restarting is attempted it acts as if the timing is too advanced causing the motor to fire against the starter but the engine starts right back up and begins running rough. If the car is left untouched for an extended period of time it will start up and running fine until the whole process repeats itself.
The only electronic item that hasn't been replaced is the wiring harness and the IAC valve.
I am out of options. It doesn't throw any codes. Don't know where else to go.
Problem occurred around 2012. Car would start but would require constant press of the gas pedal or the engine would cut. Took the car to a mechanic and replaced the mass airflow sensor. Three years and 15k miles later, problem has not resurfaced.
