Possible simple fix 200 1979

I would do the stuff on that list and see what happens. You'll need a DVOM that also measures duty cycle and a long 3mm allen wrench as well as a new throttle body gasket. The Bentley manual also has good directions on the actual CO adjustment procedure even though it's for turbo engine cars. But it still applies to the earlier K-jet cars. If your oxygen sensor is bad they cost around $20 if you want to splice the wire or maybe $30 for one with the complete wire already attached.
Putting the rubber intake bellows back on is a pain. For an easier installation see Foster's method in this previous post.
