I think I know what is wrong....I have a 00 'tour with a Zetec a/t. I recently had a hesitation problem took it to a FORD dealer was told it was the MAP sensor got it replaced. Jumped in the car went to turn a left on to the street and the thing started to buck like hell and then almost died. Got it back to the dealer-of course they didn't believe my story so the service manager drove it with me in it.It would only do,the stalling bit,when making a decently left hand turn.They figured it out to be the fuel pump.I got it FREE!! Over $500 of labor and parts because they didn't fix it right the first time. Maybe this will help you out.
