Default Need some help bad!!

I'm not sure if this is computer but I'm about 80% sure it will be....

2002 Trans Am WS-6
A4, Pacesetter LT's, TD Exhaust, lid for mods

Here is the synopsis of whats going on

No O2 sensors on the back (never installed them @ my buddies place when i put the headers and exhuast on and that was about 2 years ago)

Car is idling at 500RPM right now (yes that ******* low) or when its started it goes to 2k and then drops fast

When I let off the pedal it immediatly goes to 500RPM again

Electronics in the car will turn off sometimes when the car is turned off instead of giving you the 10 minutes it normally does to do your thing (when this happens I know the car won't start on the first try)

Battery voltage moves from 13-15 steadily (prolly from the amp to the speakers as I can see my lights dimming when bass hits so just needs a cap more than likely)

This has really been noticed at about 1/4 tank of gas left. Prior to this week the car was getting about 25MPG and was idling in the 1500 mark

The car has not died at all while driving, it only has a massive problem when its started and I can feel it being very sluggish.


what ya'll think?
