Bruno;
        For coolant temp sensor refer to page 24.62 in Bentley. Unplug
ECU and measure between pins 6 and 10 on the wiring harness plug. This
checks plug, wires, connectors and sensor. Refer to page 24.45 for
resistance vs. temperature chart. Zero celsius should give 5.75K ohms as
near as  I can tell.
        The idle switch is an exact adjustment. It is also outlined very
well in the Bentley. The idle position set screw, idle air bypass and
idle sensor should be se in proper sequence since they interact with each
other. The chances of you randomly hitting the exact combination are
slim. Get the Bentley, or maybe check the local library for one.
Good Luck

does not make contact when the throttle is in idle. Tried to adjust the
switch but the exenter screw is stuck and the allen wrench tuns inside
the head....But I did try to lower the idle speed by adjusting the set
screw to approx.800 RPM. Now the throttle switch closed in idle. However,
now the idle has become unstable (pulsating)....Unfortunaltey, there
seems to be no noticeable difference.
