Tell us when it vibrates. What speed? Does it happen under acceleration? Under braking? Do you feel it in your butt or in the steering wheel?

Probably injector(s), Bad plug(s), Dirty MAF and or bad connection, water in the fuel, etc., etc.,

There are many variables.

water in the fuel

lol, comes standard in alot of states now. bastards!

Those 5 things are a great start, still need to do my injectors. grr.

Quit feeding it quarters!

Without a maintenance history, that's all we can offer.

Has the car been doing this since you bought it or just started. I bought a 91 a year ago and couldn't understand why it shook so bad at 2000rpm. once i finally put it on a lift to check under the car it was missing two bolts from the transmission side of the driverside gusset. and completly missing the passenger side gusset. Since i installed bolts in the driver side one vibration is almost gone. now i just have to find the right one. just a thought but good luck solving the problem

Sorry all for not getting back sooner,we moved! A much bigger endeavor than I thought it would be. The car does this at Idle,however not on a cold start.Once it is warm,as soon as you crank it it wants to shut off.While driving and coming to a stop ,Then it does it and the Idle drops to 500-600 thanks james

Yeah sounds like it's a fuel delivery problem. Injectors or Maf
