    idle problem

    goes from 800 to 1500 up and down any thoughts

    Is it a slow up and down, or fast?
    If slow, most likely a vacuum leak.

          Intake leaks and/or a sticky ICV. Remove the ICV and clean it with carb cleaner until the vane moves freely. Replace and obviously cranked hoses and then have smoke test run to find other intake leaks.
          The car makes it possible, but the driver makes it happen.
