I have a 97 accord lx.the problems are when i first start up the car the car shakes and vibrates.Now when i turn the ac on it shakes more violently.the rpms starts to go bounce up and down and then it sometimes drops all the way to the bottom making my car feel like its about to die out.its a 5 speed.Thank you

 

I'd first suggest that you check that you're not dealing with an engine skip.
Does the condition clear up once it warms up?
Is there anything else that you can thing of that can help put a finger on this? The problem is that there's many different types of vibration, all for different reasons. Anything you could add would help

the vibration doesnt stop when its warmed up.i know two motor mounts are kinda worn out.think the front driver and the rear mount is going.But the vibration feels like a rumble.it gets worse when i turn teh ac on.
