the idle rpm will change depending on how the engine is being loaded. in gear, in neutral, ventilation on, ventilation off, a/c on, a/c off, cold start, warm start. if my car wasnt sitting pristine under its car cover in the garage until next may i would test it all for you with all the combinations, but i cant do that.....so you'll have to try it all yourself.

That is correct but what I feel is weird is that with A/C off under the same circumstances, in D position it would idle at 500 sometimes, and other times at 800

even if the a/c is off and the fan is still on it will be different. the ventilation fan takes power, the a/c compressor takes more power
