The cars started missing and running rough even after having a complete tune-up and after about week later it started all over and was taken into the Mercury dealership that found that the intake manifold was cracked and had to be replaced at our expense, which we just received a letter in the mail regarding a class-action lawsuit against Ford for the same problem.
