I have a 2002 Mercury Sable Wagon with the Duratec and there's an annoying problem whereby depending upon road conditions, the gas pedal vibrates and makes my foot go numb!
The dealer has replaced the throttle cable and the situation has not changed. There is no vibration if the car is in park and the engine is throttled, it only exhibits itself when it is driven (I do not think the vibration is coming through the engine compartment). The severity of the vibration depends upon road surface, it is minimal (but still present) if the surface is fresh asphalt, it it's concrete or older asphalt it is much more evident. Steering is fine with no vibration in the steering (balancing appears to be OK). Vibration with my feet on the floor is nearly non-existant. The virbation is also present through the brake pedal as felt when resting the foot extermely lightly upon the brake pedal as so not to activate the brakes.
If I have my stereo on (factory stereo Mach system) at moderate or lower levels (high levels will obviously cause unwanted vibration), some vibration is felt from the kick drums sounds and such through the pedals but it is minimal (but still existant).
I hope I have provided enough details for an expert in this forum to offer possible solutions.
