I have the same problem. It started after my alternator was thoroughly soaked one day. I figured my regulator was on it's way out but just lived with it. 18 months went by and I eventually changed the alternator but the problem still exists. So I guess that was a coinsidence. I'm wondering now if the Alt simply isn't outputing full current at idle. It would be simple enough to prove - never seem to get around it.

Does your tach needle bounce during lane changes as well (higher RPM) or only when idling at a light?

yeah it does the same thing when changing lanes too.

put a volt ohm meter(digital voltmeter) on the battery and start pulling fuses,when the volts drop,thats the circut thats giving you probems. have fun.

I was having a problem with the battery discharging at one point. I did what ThumperZ suggested and it turned out that my alarm was causing the problem. I pulled the fuses out of the alarm module and it solved the problem. Do you have any aftermarket alarm or remote starter or anything?

no i dont have anything like that no alarms or remote starters but i was looking under my dash at some of the wires and some of the splicing jobs that were done seem preety bad and not even covered just bear sire showing so could that be a part of the problem??

Bare wires for sure are a no-no. But do what Thumperz suggested to work out what circuit is causing the problem.
