[DML] Re: Idle too high, but kicks down when I tap the gas pedal



This kind of symptom will usually be caused by a misadjusted idle
micro and/or looseness (play) in the quadrant link connecting the
throttle spool to the throttle arm. Even with play in the link you can
usually adjust it so it positively sets the idle micro. I also
recommend cleaning and lubricating the throttle spool and the throttle
cable. After 25 years it may be time to clean and relube! Don't forget
to see if the carpet or the floor mat is interfering with the pedal.
The idle is supposed to be 775 = - 50 RPM's. So even at idle you are
not idling right @ 1,000 RPM's. Check that the 3 brass screws are
lightly closed. Use a meter to verify that the idle micro is being set
and is not defective.
