My whole car started shaking... Really bad vibrations ???

1911A1 · February 25th, 2007, 08:21 AM

I started my 94 gt mustang this morning and It started vibrating bad. It vibrated a little less after it warmed up but still way more then normal. No weird noises. Temp in normal. It vibrates really bad at all speeds. What did I break?

If you have a 94 I sure it has a 5.0, Mine did the same thing and I found that the harmonic balancer was going(or went) bad. This is the item that sits behind the crank pulley. Mine started to separate and actually came apart, made the engine look bad major vibration.

Mine shook horribly after it rained so i replaced the distributor cap and rotor and it was fine.

Temp was normal, bat level normal, no check engin or other lights, accelertated noamal everything. It was mainly vibrating at the main part of the engin from what I can see. I can really feel it in the stick shifter. When I first started it cold it vribrated bad but then settled down a little as it warmed up. I notice it a little less when its idleing.

When mine shook really bad, it turned out to be the driveshaft & u joints.
Man, once those were changed out, a big difference.

You are talkin about a miss not a vibration. Big difference, Check U-joints and harmonic balancer.. Awhile back my car started vibrating but only at certain speeds and I was already going to upgrade to a aluminum driveshaft and I did and that was it... Not sayin thats your problem but just a thought...

well it doesnt do it anymore after replacing the cap and rotor but i will look into u-joints and harmonic balancer.

thats exactly what mine did when my harmonic balancer went out, mine didnt look worn or anything though but you could look at it and tell it was off....
