RE: 4000 RPM Limiter

[Paul.J.Timmerman@jpl.nasa.gov]

There are only three things that can cause the early
mac-02 style computers to limit at 4000 rpms.  This is 
the limp home mode.  It means you have a bad input to the
computer.  The three are, 1.) air intake temperature
2.) coolant temp (sic?) 3.) idle position switch (?).
I don't have the doc';s right here in front of me
so I may have it partially wrong.  But you've got some
simple little electrical problem that can easily be
identified with a DMM.
