Lucas injector cleaner and some 93 octane can help with that. As for the sensor from stray bullit it's a good point. All of that stuff works together and if one goes it screws with everything. I'm sure some other guys on here have had some issues so they will chime in. On a positive note all of these little rough idle issues aw relatively minor in most cases. It's just figuring it out that's the hard part.
Okay, but if its not showing any codes... How would I know XD

My gut is telling me it's a bad vacuum hose
Which seem the most susceptible to cracking?
