I have a mityvac, but I don't really know what I'm doing with it. The next thing on my repair agenda is likely the hoses to the ICV, these seem to be a common weak spot on our old m103s and it's a cheap 'fix'.
O2 sensor was replaced about a year ago, mentioned in the OP.

Just attach the mity vac to one of the vacuum ports. you should read minimum of 12hg, 15 being ok, 17+being tight as a drum.. Needless to say this is done at idle.
Dont waste your money on things that do not need replacing. I do agree that the idle air hoses should be replaced as a maintenance item(every 15 years), but why not do it at your lesuire in the spring? It is probable that it will not solve your problem today, and they are kind of difficult to swap out.
Try a bottle of redline, its 10 bucks, and it can only do good for your car.
