Engine Mechanical problem
2002 Ford Windstar 6 cyl Front Wheel Drive 115000 miles
Car jerks or bucks going uphill (does not have to be a steep hill) at a steady speed. Can accelerate past it and it runs OK. Hard acceleration seems to be OK also. Have replaced plug, wires, fuel filter, 2 upstream O2 sensors, checked air filter, fuel pump pressure,cleaned throttle body and mass air flow sensor, also replaced intake manifold gaskets. Running has improved but still have the jerk uphill. No lights are on.
