High electrical load is suppose to trigger a higher idle. It's normal. Idle should also rise if you turn your rear window defogger on and/or turn fan blower to high.

Is not the same as this:

A loping idle that rises and falls continually, (probably gets worse once warmed up) is usually a result of a vacuum leak in my experience.

Yeah if your idle is rough like that, a vacuum leak is likely
