Shakes or Wobbles problem
1990 Plymouth Laser 4 cyl Front Wheel Drive Automatic

Hello, I have a 1990 plymouth laser rs with the 2.0 4cyl automatic. The car runs fine, driving around doesnt have a single problem, except in idle. the body shakes hard under 1200 rpm. And I'll have the idle adjusted to 650rpm in idle, and once i put it into gear it drops to 300rpm. I've checked the spark plugs, they're all fine. So what do you recommend? thanks -Matt

i advise you to repair it. only because the vibration will start to allow this whole cars assemblies to fail as the shaking affects anything attached to the powertrain. ok? if you start to move the throttle in idle without a reset, or calibration, it can cause trouble, does it have a miss? is 1 cylinder out?
