Any idea what else could cause a simultaneous increase in idle speed and discharge?





If the Alternator is not charging you will have a discharge, furthermore if the alternator is not charging it will not be putting a load on the motor so the idle will be higher than when it is charging.

Allen Here's a novel idea, let's not throw a bunch of parts at the car hoping it will fix the problem and instead spend a little time diagnosing it first. Life was a little easier when I was just a wrench.
