Just wanted to post up some interesting findings with my wife's POS Ford Contour. 2000 Ford Contour, close to 99000 miles, 4-cylinder engine. Hesitation and bucking problem started over a year ago, and only seemed to happen when it was low on fuel. So my wife just kept the fuel tank over 1/4 all the time. It started getting really bad recently and the car threw an engine code: P1383, which has to do with the cam shafts and timing. I checked the Contour forum (yes, there is a Ford Contour forum, much to my surprise) and got the logical culprits. So I replaced the cam position sensor, cleared the code, it came back with "Exhaust cam timing retard". So I figure it's the variable cam timing module. Car needs a timing belt, water pump, accessory belt job any ways, so I take it into the shop (I don't have time to do this myself). Come to find out the timing belt was missing 6-8 inches worth of teeth, which the shop had never seen before: "Usually when one tooth goes, the entire belt goes". Luckily the belt did not fail and we got away lucky with no head damage.
Also found out that the initial hesitation problem is likely a fuel pump issue. I'll be replacing that in the coming weeks.
