Alternator noise and slight engine miss, related?

I'm noticing the alternator doing a faint hum/purr noise on and off. Mixed in with that, the engine is doing a faint miss also.

I test the battery to see the voltage and it's holding at 14.4. Is AMPS a bigger factor in this(measuring output from alt) to determine if the 2 are related?

Also, what are some common issues that attribute to a miss on the 4.2 with fuel injection? I might be chasing something else besides the alt.
