I know there are other posts about "bucking" but they didn't seem to be similar to my problem.

My car idles fine. When driving I'd say this problems happens about 15% of the time. I press the gas, begin to accelerate and then the car just stops accelerating...then accelerates, then stops again. hence the "bucking".

The problem is worse when it's very wet out. It's the worst when the car is just started.

I changed the plug wires, spark plugs, distributer cap and rotor, but nothing helped.

Thanks for any possible help.
