more on '87 TQW idle problem?



  Here is some more accurate RPM data on the problem:

  A/C off: RPM starts at 1100, nice and steady, then slowly increases
  to 1400 RPM, then instantaly drops back to 1100 RPM and repeats
  at about 3 seconds per cycle

  A/C on: just the same but RPM start at ~1200 and cycles at about
  2 seconds Vs 3/w A/C off

  NO change whatsoever with idle solenoid disconnected, A/C on or off.
