There are many reasons why the idle speed might be too high; here are a few that you should check out. Idle speed adjusted too high. Ignition timing too advanced. Vacuum hoses disconnected. Throttle valve switch misadjusted. Intake manifold nuts loose. intake air distributor output hoses mis-installed and leaking. etc. Jim - ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ------------------------------------------------------------------- Search old messages on the Web!
