Daughter called for help. Increased idle started suddenly, not
dropping engine speed at stop light. If left without brake, will
reach about 20 mph. Stayed same when started after parked overnight.
No help spraying linkage. When I see it later this week, will check
linkage for frayed cable. Is there anything else which commonly
causes high idle? Clogged PCV valve? Bad vacuum line? Bad
electronic component? Rat nest under air cleaner? She states no
symptom above 30 mph, and accelerator peddle does not stay down or
appear binding. I just want to be able to test all causes, and save
her a buck.
