Just changed head gasket-no problem. However, when I started the engine, it immediately "raced" at extremely high RPM (shut off immediately). Could see nothing wrong, so carefully started engine again (raced again at entremely high RPM) and shut down immediately. Is this a problem w/idle control valve and, if yes, how to fix (or replace??).
