Hello, I have a 93 buick lesabre that stalls while driving at times, and then cuts off when i turn corners sometimes. I just had the fuel filter changed, and the vacumm hoses checked and repaired. Can someone help me with what I should try next?

check you fuel pump and sending unit. Maybe even your plugs and wires

mine just started this...first cutting out around corners and then on fast accelerating ...now coughs and sputters at anything over 1/3 throttle..any ideas....im thinking fuel pump

I'm agreeing with you on this, might be the sending unit too though

The sending unit affects the operation of the gauge only. It can be checked by connecting a DVM to the leads, and slowly move the float arm. The readings should change smoothly, in both directions. You might also check the fuel pressure. If low, the pump is likely the culprit. This sounds like guilding the lily, but I don't like changing parts before determining whether they are defective. Ray
