trying to stall??

This is really bugging me

The other night I went to start my car and the security light was on and it would not let me. I unplugged the battery overnight and the next morning she started right up BUT......

When I have my lights on, stereo on when I come to a stop the idle drops to 500 for a second or 2 then goes back to 900. the oil pressure follows the drop in rpm's as well but it doesn't completely die. when I shut off everything it doesn't try to die so I thought it might be a ground problem or because the pcm is relearning. It does this when I first start the car and every time I come to a stop for about a half an hour. I am going to remove the amp and wiring first to see cause the last time it did that my stereo shut off and ejected my cd like it reset itself.
