I've got a '99 Ford Explorer XLT w/ 96,000 miles on it. When I start it up in the morning in winter it struggles but finally kicks but then you have to give it alot of gas to keep it from stalling for the next five minutes. And when you are driving it, it runs pretty rough and will stall when you are turning corners, locking up the power steering. We had it sent to an auto repair place but the problem was not fixed. This car is pretty similar to a '99 Ford Ranger. Any sugestions would begreatly appreciated.
