Why does my car jerk when I accelerate? on 1997 Ford Taurus

Anytime I accelerate, whether I've just started the car, or I'm a stop light, my car starts jerking as if my tires don't want to spin. My check engine light is on but it's because my catalytic converter needs to be replaced. What could be causing the jerking?

How long ago were the codes read? If light is already on , how do you know when an additional fault code has set ??? Leaks between TB & MAF? Does it matter ??????
