    If your using your air, a big stereo or anything that draws power from your battery your alternator will kick in to charge your battery. this will cause the engine to rev up a little. You will hear a little noise from the engine. I hope that's all it is .

    I switched off the engine & let it sit for several hours, then switched it on, stayed in neutral but I could still hear the engine sounding as though it was ready to start, then it stops and 10 seconds later to repeats the process.
