OK now that I have the vacuum lines all nice and sealed up and the idle/fuel mixture nice and sweet I got to thinking just how DOES one adjust the idle speed on an 85' with lambda? Of course the idle is supposed to be controlled by an electronic module, but there has to be some sort of method to tweak the speed slightly? I'm idling fully warmed up at around 600RPM on days with low humidity in the air and maybe 550-560 on humid days or rainy days. Would like to be able to tweak the speed up maybe 50-60 RPM or so. Anyone know how to adjust it on my model??????????

The only way I could think of, and I wouldn't know how, is to trick the idle control valve into thinking the engine is running 50-60 slower than it actually is.

You might be able to get it up a few rpms with the idle mixture screw.
Be careful, it only takes a very small part of a turn. Clockwise is rich.
Also, your ICU could be going bad.

You can't adjust the idle speed on these. /end
