[DML] Re: Constant High Idle Speed

["content22207" <brobertson@xxxxxxxxxxxx>]

You could well have an ECU problem. Idle air regulator responds to
it's signals.

If you want to bypass CIS, there's a manual idle speed circuit already
built into the upper air assembly. eMail me off list
(brobertson(at)carolina.net) and I'll explain how to use it. Note that
this is *NOT* a modification -- you simply deactivate CIS and
reactivate the manual circuit that preceded it. Can switch back
whenever you want.

Or you can just crack the throttle plates like an old fashioned
carburetor (a List member is currently idling so with excellent results). 

Note that either non-CIS method will not give you fast idle without
additional hardware (aux air valve).
