After changing my serpentine belt on 02 corolla le, car started to shake while idling in Park or Neutral. once i start driving and car warms up the shaking stops. could this be because of the new belt or something else?
please help.
thank you.

Could be from a number of possibilities. Was it shaking before you replaced the belt? Did you route the new belt the same way as the old one? Is the new belt riding the pulleys correctly (centered)? Did you damage the belt tensioner when you replaced the belt?

Possible that the shaking is not even related to the serpentine belt change. Could be anything from bad sparkplugs, worn engine mounts, bad tank of gas, weak ignition coil on plug unit, dirty MAF, dirty throttlebody, etc.
