I have an '83 240 wagon, and I need to get it through emissions, but
they won't test it because it's idling at around 1250, and I need to
get it down to 1100. Could anyone help me out with this? I have very
little working knowledge, but would like to attempt this myself, if
it's easy enough.

Look for vacuum leaks. Change the air filter if you haven't already.

Yoko Onos' former driver tried to extort $2M from her, threating to
"release embarassing recordings...". What, he has a copy of her album?

It should be idling at 750, something is definitely wrong. Vacuum leak,
timing too far advanced, throttle linkage adjusted wrong, etc. If it started
doing it on its own, something has broken and needs to be fixed.

Perhaps the Idle Air Control is malfunctioning?

Test it by pinching off one of the two rubber air hoses that attach to
it, and see what difference it makes in the idle.

If there is no change, suspect the part needs to be cleaned with carb
cleaner, or replaced.
