hi just some adice from the technical engineer types really?!

when your car is cold ( eg a 1600 zetec)
and started at idle the revs are 1200rpm!!

once warmed through the engine idle revs drop to say 850rpm

am i right in saying shutting down during the 'high idle' period that it can lead to borewash as the excess fuel needed to run at idle has no where to go apart from your sump of lovely expensive oil??


thanks for any detailed response in advance
