I have a 94 LeSabre. It's a great running car, in good condition. Just out of nowhere, it began shaking slightly at low speeds, only sometimes. It shakes terribly around 65, always, It feels like it's shaking in the middle, like it's going to fall apart. It shakes the worst when the car goes up any type of incline.. I've added fuel injection & carb cleaner. Ran OK for about 5 miles, now it's doing it worse. I have a 94 LeSabre. It's a great running car, in good condition.

I had this problem and I replaced my spark plugs and wires and the shaking stopped.
You can start to make sure that the wires on the spark plugs didn't shake loose.
If you have a bad spark plug then the engine will shake, sometimes violently, especially at high speeds or at the high rpm of any gear at lower speeds.
Take a REAL GOOD Look at your Half Shafts, sounds like to me that your Inner portions of your Half Shafts my be coming apart, and the bearing are shot in them, You don't want them to come apart on you at high Speed, and with the added torque for the Pull up hill, they might be binding.If that's not it, A wheel aligenment and Balance just might be you solution.
Im willing to bet more than anything that u need a wheel balance on both front tires. dont let them talk u into doing the back i'll guarantee that will fix ur problem. it happened to me too many times for me to be wrong.

Hello: Check your spark plugs, spark plug wires, distributor cap and rotor, Also think about the last time you replaced the fuel filter. If the car sets for long periods then the gasoline may be contaminated.
I have this same car with exactly the same problem. Begins shaking at 40mph and stops shaking as soon as you let off the gas, but then begins again as soon as you press on the gas and smooths out as you get over 50. And the shaking is not felt through the steering wheel. Solution: Replace the transmission mounts. There are two of them, one on each side mounted on the frame right next to the shock strut. There is also a front and rear engine mount, but I replaced the two as described and shaking is gone.
thank i'll check the mounts
