My 1990 S13 runs strong with its KA motor, but at about 40MPH when i let off the gas usually the car starts to shake violently, most noticable thru the wheel and shifter. Any ideas what is causing this? Im guessing either the suspension that took a hit prior to me owning it, or the oil back flow restrictor.
