whenever I stop, the car idles way down and the ampmeter drops along with the lights dimming...any thoughts? IAC? TB??

I had the same issues once, mine was an exhaust leak though.

Check your IAC. If it's really black inside, clean it. Clean your MAF screen as well as check your TPS voltage. Check for vacuum leaks too.

With a voltmeter. It should be between .97 and .99.
