My daughter is experiencing stalling with our 2003 Sable after the car is warm. This occurs after highway speed, slowing down, and beginning to acelerate. The car will restart after a brief period of time. The condition is intermittant.
She took the car to a local mechanic and they replaced the fuel sensor on the rail. This did not correct the problem.
I plugged in my testor when I returned home and received code P0191.
My question is fuel pump problem, or another item?
