Many thanks for the prompt reply - unfortunately went ahead and
changed the fuel filter and you are right. Am going to check rad
coolant as you suggested - also book a valve adjustment job as it has
206,000KM (130,000 miles)- on it with no valve slop. An interesting
side note to the fluctuating idle speed of 900 - 1600 rpm's on the
Tach is that as soon as the vehicle is put in drive - the fluctuations
end and it even's out at a steady 900 rpm's
