OK...my car is having the same problems most of you here have discussed. It is the 2.5 liter engine. At 100,000 miles I had Ford do a tune-up: they changed the spark plugs, fuel filter, air filter, changed coolant, replaced the water pump, serpentine belt, transmission fluid, O2 sensor, idle control valve, and also the MAF sensor (but NOT the plug wires for some reason). All of a sudden my car started the bucking/hesitation/stumbling. I went ahead and replaced the fuel and air filters to see if that helped...it did not. The car only has 130,000 miles on it now - the plugs and sensors should be fine...so, my question is could the PLUG WIRES be the problem? They are 7 years old and have 130,000 miles on them. I admit I know nothing about cars...and this is bugging the piss out of me. I am a senior in college (a.k.a poor) and I need this car to last another 6 months at least until I graduate! Any help would be GREATLY appreciated. BTW, the check engine light is NOT on to indicate any emissions/sensor troubles, and the injectors were cleaned during the tune-up also. Thanks!
Try copper plugs and see if it solves the problem ($5 from Champion). It did on mine. I truly believe that there is a bad batch of Autolite/Motorcraft plugs out there that is causing all these problems.
