2000 Intrepid R/T rough idle

[GR8WHT]

I just got a 2000 Intrepid R/T. When Idling it seems rough, like it missing. Off idle it runs fine. If in drive it idles at 550 rpm and 600 in neutral. Driveing it seems fine, just a bumpy idle. It is smoth for about the first 10 sec sitting at a light and then it starts to shake. Has anybody seen this?
3.5L autostick. Also does anyone know of a location for TSB's?

Just got a R/T last week. Bright silver
with aftermarket agate leather interior.
Just had Viper Ultra alarm put in and had
windows tinted. Have also noticed that rough
idle also. Seems like sometimes its ok and sometimes its a little rough. Am planning on running premium when I use up the tank of gas I have now. Also ordered the KN air filter (for 300M). Also, want to find out what aftermarket exhausts are available for the Intrepid. Please let me know if you know a good source for Intrepid parts.

Just wondering, what kinda tires are on your R/T. Are they the standard 225/60 Eagle GA's put on the other models or did it come with better ones. By the way, I put Dunlop SP Sport 5000's on mine and it handles great, I haven't even squealed em yet around turns and i was goin' about 10-15 over the limit while doin' it.

Michelin 225 55R 17 V rated HVmmS (not sure on the letters) came with my Intrepid R/T White. I added the Deck Spoiler (comes prepainted) and it looks great. Planing to get a K&N Filter. Dual exhaust is do-able because if you look unnder the car its duals back to the first muffler. 3 Mufflers GEEZ!!! can you say backpreasure! I tried various fuels from 87 octane to 94 octane. With a 10:1 compression ratio you would think it wants premium. The best I fouund was the Mid grade 89 stuff. She (GR8WHT) sounded better and seem quicker than on the 93 and 94 octane stuff. She is still new but has picked up in performace quite a bit over the first couple thousand miles!
