Classic symptoms of a failed idle stabilizer control unit:

ebuilt.html Those exact symptoms happened to me--the 2000 rpm revving is
typical, as is stalling out. These are all pushing 30 years old, and the
internal components are failing.

Checked injectors for leakage. They are perfect with no drips etc. Checked
temp sensor that is new and it is working. Worked on the drive side
injectors seals they are tight and seal properly . Still same problem! Grr!

each pair of injectors out of the intake without disconnecting the hoses or
wires and using a container to catch any drips, pressurize the system by
turning the key a couple of times.

restarting I'll sit there and raise the idle to about 2000 rpms until it
clears out 15-20 seconds. After that it runs perfect.
