shuddering/shaking

1996 RS. 122,XXX miles

i have 2 questions,

numero uno, normal driving and when im gunning it, it goes, just fine. not really any hesitation, but when im driving if i let go of the gas the car like shakes for a second back and fourth.

number two, the car shakes when i get it past about 65, i havent taken the car over 85 yet ### im worried what will happen, my alignment is off, pulls to the left alot.

wasnt really a car guy til the gas hit 4.50/gal had to get rid of the 351 so im used to old lifted trucks.

so yeah NEWBIE

help me out if ya can,
thanks guys

is all this shaking in the steering wheel? the shaking over 65 sounds like unbalanced tires. if you dont want to pay for a balance you could try taking the tires off and cleaning the inside of the rims really good. brake dust can build up on the inside of the rim and cause them to be unbalanced. the decelerating shaking, im not actually sure.

Check the axle nuts and lug nuts. Sometimes people don't tighten them up enough. Also when you got the car in the air pull the tire to see if there is any play. Might be a wheel bearing or something as simple as a tire pull.
