Open the hood and rev the engine, see if the engine 'rocks'-might be a bad motor mount, or tranny mount.

The timing belt just came off of my car last night on my 1994 oldsmobile 88 and i cant figure out how to put it back on need some help maybe send a diagram step by step would help

The 1994 Oldsmobile 88 does not have a cam/timing belt. It uses a chain so I am assuming you are talking about the serpentine belt. There should be a routing diagram of the serpentine belt under the hood somewhere. May be on the underside of the hood or on the radiator mount. Also can be found in your owner's manual. If the belt came of you need to find out why. Either the belt is worn out or the tensioner is defective or both. I would suggest you replace the belt for sure. Here is a diagram of the routing of the belt on your 1994 Olds 88 with 3.8 V6. clay58_18.png
