I have had a persisting problem with my 93 Honda Civic Dx. The problem is when I accelerate the car begins to bob back and forth violently,its really dangerous and I am not sure what the problem is so if any body has a diagnosis of the problem I would appreciate it.

 

Are there any Check Engine lights on? Have you done anything to the car recently?

hmm...weird. well this is what i'm going to suggest to you.
follow these steps first:

if nothing comes up, then maybe bad gas? when was the last time you did a tune up?

 

Just took a quick look at your profile, are you really 14? I've had a simple solution that I've been biting my tongue about, but then I realized you might be new to this car. Is this only in like first gear at light throttle, or in any gear at like full throttle at any speed or something? Because it could just be that you're not used to it. When I just got my civic, it jolted violently, because I was not used to the throttle coupled with the light weight of the car.

 

It happens in any gear and only at low throttle, and i also thought it might have been because of my lack of car experince but my brother tried to drive it and the same thing happend to him.

have you tried the steps provided in the link i gave?
sometimes a CEL would come on and turn off, but the ecu should have it saved. doing this would pull the code and possible to the answer to your problem.

 

No check light huh? With those symptoms I would check the TPS sensor first! First overlook everything in the engine bay? Loose ground? Loose Plug wire? Search TPS sensor!
