idle stab system
Here I am again, confused and seeking info from you, the experienced. Still
cannot figure out the cause of high idle on my 86 5kcst (MC engine). For
some reason my Bentley does not give the checking procedure for ISV system
on this car, therefore I used the one described on page 25.7 (WU, KZ
engines) because the relay wiring description fits mine. Everything was OK
except the voltage on the valve with ignition on was 3V instead of battery.
The voltage on my 87 5ks ISV is battery but its different system according
to the diagram. So what the correct voltage reading should be on MC's ISV
with the ignition on? Or maybe there is some way to check the ISV relay? My
sincere thanks for your precious input.
