90 celica vibration

I just purchase a 90 celica gts and it has a wicked vibration that i cannot seem to find
ok on acceloration but vibrates when the motor levels out\
any ideas from you celica owners
vibrating celica in oklahoma!

i forgot to mention its a 5 speed!

about where do you think it is coming from?

cannot tell where
it just seems all over

alright well haha thats never good but i would just let your engine run at idle and pop the hood and look for loose brackets and stuff liek that and in your dash make sure all the screws are tightened and general stuff like that... all i can think of really

Do you feel the vibration through the steering wheel? Also, does it vibrate at any speed when the engine levels off or only in a certain speed range or only above a certain speed?
