Shakes or Wobbles problem
1991 Cadillac Deville V8 Two Wheel Drive Automatic 71546 miles
Had a new fuel injector installed and it went bad immediately. Mechanic replaced it thinking it may have been defective, blew out that one too. Mechanic says he doesn't know what it wrong, computer does not show a problem. We do not have a cadillac dealer within 350 miles. Any idea what could be wrong?
