Question
"We have a 1996 Ford Windstar LX, 3.8, After the engine gets warm and you turn the steering wheel full right or left it will kill the engine. The other day after driving it awhile if you turned the wheel about an inch it would die. We have check everything thru ALLDATA. We have replaced the IAC motor no change, Computer, Powersteering pump, intake manifold gasket. We get no codes, this vehicle has no power steering pressure switch. It didn't come on this vehicle. We have checked all the sensors, checked for vacuum leaks. have done everything ALLDATA has said plus everything other techs have suggested. Got any ideas??? Oh the vehicle runs great, no hesitation, miss, bogg, great performance. Doesn't run hot. ";

Answer
Charlie,

I hate to tell you but it sounds like you have a vacuum leak. Have you checked the vacuum lines at the throttle body? Check them from the motor down to the transmission. The only other thing I can think of to tell you to check is the Mass Air Flow Sensor (MAF sensor) or the fuel pressure regulator. I hope that this helps and if you need further assistance, please do not hesitate to contact me. Good luck.
