[W126 Coupe] Slightly High Idle - Possible Causes

[Dick Spellman]

Hi John:

Test the coolant temp sensor which is the 4-pole on an 89.  The 
following presumes you have the manual, if not let me know.  The chart 
for B11/2 resistance readings is found in 073-121, page 31.  Test the 
sender for both diagonal terminals.  Then complete the harness test (n) 
that follows.  Are the readings in range?
