Just bought the lovely 94 GXE. In some days after got the vibration. It starts and stops time to time. I didn't notice any engine power reduction in such moments. This thing is really disturbing me.
Any ideas?

is the vibration in the steering wheel or somewhere else?
if its in the steering wheel, you might want to check the balance and air pressure in your tires.

 

It's not even related to if the car moving or not. I mean it can happens when I'm staying at the traffic light as well as when I'm moving.
I can feel this vibration everywhere in the car, not only on steering wheel.

 

i get that 2, but only at certain speeds, like idling and b/t 45-60 coasting, not accelerating...however, im not really sure what its from so dont ask me lol...when idling the rpm's r drop off when it happens (from about 700 normal idle to <500 when it shakes) so i'm guessing its a bad sensor or sumthin...

If you get this vibration even with the car in park it's most certainly engine related. You can try to pinpoint the problem by removing all the accessory belts and *briefly* re-testing the engine for vibration. If the problem is gone, then it's caused by one of the accessory items.

Maybe a fuel pump? Just a guess, but, if when it shakes, it feels like it's about to die, or does die without stepping on the accelerator, is what it'd be.
thats all I've had with that..

 

Well I figured it out myself. The problem is in radiator fans (I'm not sure about how they are called by manufacturer . I mean there are two fans in the front of radiator. I definitely found that they cause the vibration while working. When the fans stopped rotation the vibration ended.
Does anybody know how to fix it?

 

Those fans may vibrate little if there's a problem, but I can't imagine it would vibrate enough to shake the whole car.

Over time, your throttle body gets a lot of gunk on built up on it which will make the engine idle a bit rough.

Get a can of throttle body cleaner, and clean out your throttle body. This should help. It's pretty cheap also.

Take a look at this handy webpage.

I figured out that the fan blade is broken. Plus fans assembly is unfastened at the bottom. That's enough for making bad vibration.
But anyway thanks for the hint.
