My car has developed an extremely annoying bucking under acceleration. It started about a week ago, and at first it would only happen while accelerating out of a fast turn. But now it does it all the time while accelerating. It's like the car is oscillating between half power and full power, making it lurch-slow-lurch-slow-lurch-slow. It's like you're riding a bucking bronco or something. The only cure seems to be to get off the throttle completely, upshift, then slowly accelerate.

Anyone have any idea where I should start looking first?

I'm surprised that no one has mentioned the fuel filter.
