Bill and I spent the day yesterday replacing the timing belt in my contour, after a bucket full of swearing and a lot of trial and error, we got the belt perfectly timed by about midnight. Out for a drive, babied the car down the road, then we got to 3rd gear and it started to buck horribly, in a pattern, no power at all. Skipped third went to 4th, was all fine and dandy again. We figured time for plugs and wires, so we got motorcraft plugs and duralast wires (yeah I know, but it was all that was avaliable at the time), swapped it out, everything ran even better, until the motor was warmed up, then surely enough nasty bucking under load, but now it doesnt just do it in 3rd. I can get it in 2nd and 3rd, and even occasionally in 1st (rarely though), Bill's dad seems to believe its time for a new coil pack... any suggestions? The timing belt is running beautifully right down the middle, perfectly in time, I have no CELs, and new Plugs and wires.
