    Our 1995 SL 2 103K has started idling at 1500-1600 rpm. Cold hot doesn't
    matter. Sometimes it will drop to 900 but for no obvious reason. Checked
    cable and linkages all seem ok returns to stop etc .

    Any input ?

  2. ....I thought I read/skimmed in the threads something about a failing coolant
    temp sensor and high idle. Maybe do a search in the Google newsgroups, and
    or wait for someone else to answer here...

  3. Try the TPS sensor, my 96 SL@ would rev high rpms when I had a vacuum
    leak, or vacuum hose was not attached.

  4. Before playing sensor tag, pull the throttle body out, clean it and the
    IAC, then make sure every connector's seated right over there. Also,
    look for vacuum leaks.

    Then, I'd look #1 at the temp sensors. They're cheaper and easier to
    swap out than the TPS...
