I am having an intermittant problem with my 380 SE.
Intermittantly it will have a high idle 1500-2000 RPM
I have checked for air leaks and found none using the can of
brake cleaner method.
if I unplug the idle valve the idle raises to about 2700 and it
drops back down to the 1500-2000 RPM range when it is pluged
back in, so I know the motor is working.
also sometimes it idles happily at 700 rpm without a problem.
any help would be apreciated
