RE: [DML] Re: 3 post idle microswitch

["Elvis Nocita" <elvisnocita@xxxxxx>]

Well Martin,
the idle switch doesn't turn the idle ECU off at all.
Instead it rises the idle speed to about 1200...1500rpm.
Why ? because it would never be fast enough to jump in and to catch 
the engine before going off.

Ever wondered why idle is so high when the switch isn't being pushed but
the butterflys are completely closed ?
No, ignition advance isn't the only reason.

While we're on the subject of the iddlsespeed valve: Exactly WHY does 
the idlespeed system need to know when to turn on? If it were hard-wired 
all the time, surely it would just close when the throttle wasn't at idle?

I've adjusted countless throttle plate screws,  throttle link rods and 
springs. it's amazing what 5 minutes spent on a car will do for a smooth 
idle :-)
