1993 Acura Legend rack and pinion

I took my 1993 acura legend for a drive today. I checked on the things you told me to the car does not jerk when I go in reverse. The problem is when I accelerate when I go over or should I say when I hit 10 miles an hour the car jerks. It's just one hard jerk if I push on the gas lightly you do not feel it as bad other than that the car is very strong other wise no problems it can really get on your nerves I want to get looked at but I do not know where to look can you please point me in the right direction. Thank you any more questions please ask.

1993 acura legend, my cars d4 light does not blink never has. You can start the car it will jerk hot or cold it will only jerk one time when the car accelerates to ten miles an hour then you will not feel it again until you stop and accelerate again. I was told if the rack and pinion was bad it would jerk. But it's not the steering wheel jerking. It's like the whole car get's a hard jerk forward the it's fine. My steering is fine very strong and stead. It's not the feeling of a steering wheel being pulled to the side. Please look in to this. Thank you for your time any more questions ask and i'll let you know. It does happen with hard acceleration. And every time I take off the only time it does not do it is when I take off really slow, it probably does it, but I guess you can not feel it if you accelerate slow.
