Every time I come to a slow stop. The RPMs start going up and down from 500-600. Sometimes it'll dip down all the way to about 300. It'll stop as soon as I come to a complete stop. It won't do it at all if I'm stopping right away. It gets annoying at night when the lights get dimmer everytime I stop. And during the day when it's sweltering and the air-con doesn't blow as hard when the RPMs go down. Anyone have an idea of what it could be?

I would guess fuel restriction somewhere...

I am sure there is someone that knows either because they had it happen to them or they worked on same problem.

LS1's are wierd like that but 300 sounds a bit too low. i would replace your fuel filter. it sounds simple but you would be suprised how much a new one will free up the flow.
