Default Idle Questions

I was having some idle issues where if I was sitting in traffic and the radiator fan would kick in and raise the idle past 1k and it would fluctuate and return to normal after the fan kicked off. I cleaned the MAF sensor and the car not only gets better gas milage but when the fan kicks on it doesn't fluctuate as much, it will go to 1k for a few seconds and return to normal.

Is that normal for the idle to go up when the radiator fan kicks in? It's much better than what it was, just thought i'd ask.

check your battery voltage and grounds... if battery doesnt have enough juice, the draw could put strain on the electrical system/alternator, and cause the motor to rev to get current flowing from the alternator. not saying this is the problem, jus something to check
