Here are a few things to check that aren't that exspencive to do. check you'r o2 scener and the map scencer.try tapping on the cadiletice convertor to see if can hear any rattling if there is any rattliling the cadiletice converter could be clogged and will need to be replaced.You can also have the emission control module tested to see if it working properly.

rack and pinion is the steering wheel joint, so if the steering wheel shakes or handling has decreased, then i would say it is the rp. , also check the wear on the tires for uneven wear, it could be alignment, does the steering pull to one side? it could be motor mounts just find the bolts and check em wiht a torque wrench, also inspect mounting bushings as well. to check trans. give it alot of gas to get past 35-45 mph and the shaking should go away at higher speeds, if it doesnt then its the trans missing "third".

Okay, you either have to get some really expensive aftermarket motor and transmission mounts, or go with OEM from dealer. I did both. you MUST make sure you follow the Haynes or Chilton's manual on setting the engine and transmission at the right degree of rotation, then tighten all anchor bolts to 89 ft-lbs.... i did this and it reduced my vibration tremendously.
