Hi All,
A friend's 1989 Jetta Cabriolet has a problem with its idle. When the engine is cold the idle lopes up and down, from about 600 RPM up to
1500 then back down again. When the engine is warm it still does it, but not all the time.Any thoughts as to what I should check?
Thanks in advance - Note that email address is fake, please reply here. Cheers, Geoff Glave Vancouver, Canada
