does it matter whether you go around a turn and then gas it or does it do it all the time when you give it the gas. sounds alot like the same problem i had a while back and it was the fuel pump. if you take it to a ford garage(which by the way GOOD LUCK!!!) ask them how many contour feul pumps they have replaced.some friends of mine who work at a ford garage told me that they replace 2 or 3 a week.anyway if you are lucky enough to have them test drive your car make sure they put a fuel pressure guage on your car and then test drive it. when they did thid to my car the psi from the fuel pump dropped to 2 psi!!! and so there was the problem. oh yeh by the way this was the third time i took the car in for this problem.
let us know what happens
