First of all, I just wanted to thank the group for all of your help! Got my 05 Light Platinum V yesterday. I had a nice 4 hour drive through winding mountain roads to get home. The V was like it was on rails, breaking the 150mph mark and I felt like I could steer with my knee! Ran into a Mercedes CL 65 AMG (600+ hp 700+ lb-ft torque and costs over $200k!) along the way that was ready to play. I was able to run with it through every turn and pulled away a few times...It was awesome! When we pulled up to the toll booth he gave me a thumbs up (I had the temp tag and dealer plate so he knew I just bought it), rolled down the window and said that he had no idea that a Cadillac could take the corners like that!!!!

Anyway, the car is used...so I expected a few problems but wanted to ask you guys if some of these are normal:

- Rough idle. The car idles a little rough. Nothing too bad, but a little bit of shake at a stop light.

- Shake after turning off the igntion. When I turn the car off, it gives a bit of an extra kick.

I think I have the diff whine problem. At highway speeds, I hear a whine in the back when giving it gas, but not while coasting. What do I do about this?

The tire pressure monitor has no display...why is this?

I also had the shift knob assembly come right off in my hand when I hard shifted into 2nd. Is there a way to secure it (screw?) or do I need a new one?

That is all for now...I am sure I will have many more questions down the road!:)

Rough idle is normal, its an LS6!
Extra kick after shutdown - check motor mounts.
Whine, wait for it to grenade...all you can do.
TPS...go thru and reset your TP Sensors, see the faq
Shifter has a TSB...let your dealer know.

:thumbsup: Congrats on your new ride...post some pics

Your concerns

1) Normal....Stealth V's tune may help alittle bit ....but I like it
2) Normal
3) Complain enough times when it becomes bad enough and maybe just maybe they will replace
4) Maybe dealer has it disabled or needs to be reprogrammed have it looked at and fixed.
5)Shift knob is pressed on and supposedly sort of latches itself in , no set screw is used. I replaced my shifter with a momo shifter. When I replaced I simply was able to put car in reverse and pull it right up and off....maybe yours either wasn't latch in properly or maybe it is worn somehow anyway have it looked at.

Again Congrats and welcome to the world of Mods
