I have a question. Sometimes when accelerating, around 2000rpm, the power of the engine goes away for a fraction of a second, making my car wobble for a very short time. What could actually cause such thing? My father suspected that the problem is in the gas pedal system. He took it totally apart and have cleaned it for like 3 times already. The "wobbling" decreased, but not totally gone. It doesn't affect the driving much, but it's still good to know what causes this. We could try to find a solution for this in a Ford agency, but it's gonna cost us some money again.
