Car Trouble

I have replaced the spark plugs, wires, distributer cap and rotor. As well as the valve cover gasket and had the timing adjusted.

When I drive my car (1988 Honda Accourd LX, w/ 230,000miles 4cylinder) it spudders when accelerating as if it is trying to shift. When I accelerate the car fells as if it jerking back and fourth. I have no problems with the clutch or shifting in anyway. Up until recently it would only do this when the car warmed up. Now it is doing this when the car is cold as well. Anything you could suggest would be great.

Thank You,
Nick
