another question here about my iroc its a 305 tpi. fairly often while i accelerate hard or soft the car shakes. i was wondering what could cause this and if new plugs/wires/rotor might fix it.

 

Have you inspected the plugs/cap/rotor/wires for cracking, arcing, fouling, corrosion build up yet?

 

not really ive been working a lot lately and havent had time to go over the car. but i definately will thanks.

 

Might want to check the motor mounts as well.

 

Drive shaft bent or warped? But I suppose if you let off the gas mid-shake and the shake goes away it wouldn't be the shaft.

 

Yup most likely plugs arent connected correctly, might have one switched around with another one

 

I think it's impossible to assume something like with the few details provided. There are tons of things it could be, hell a bad ground. Just easiest to inspect the parts that are easy first and work you way up to the more difficult stuff.
