I somewhat new to mustangs. Ok this is my first running mustang got it last night. I was driving around today and the thing shakes really bad when you let of the gas at anything past second gear. Its an 88 lx hatch. I think it might have something to do with the large 295/50's(ridicolus I had some on my 70 Chevelle, but that car was a beast) on the back. I check the U-joints and the seem fine there not clicking, some of the bushings look alittle worn, and im proably going to replace the tie-rods this weekend. Its running a little rich, and the clutch sometimes makes a thumping sound if I get on it.
