the car has done this since i bought it in jan. of this year. i just installed new plugs, cap, rotor, wires and a holly anniahlator digital ignition sytem. it only does when i mash the pedal to the floor and only in the uppper rpm range from say 4500 to 6000 rpm. it just stumbles for a second and the takes off from there. it does not do it from like 3/4 throttle acceleration even when i go into the same rpm range. its an automatic 1991 coupe. i know its not the tranny slipping in case someone was going to suggest that! any ideas???
