Hey, my STS is sitting at 105,XXX and its about time to get a tune-up now, the car has a slight vibration at idle and sounds a little loud when i hit the gas etc... what exactly consists of the tune up for the STS? and how much does it range from usually? thank you.

Cake. Plugs is it. Coil over plug.

Yep, clean the coil contacts and replace the plugs with OEM ONLY, Northstars HATE anything but. Pretty easy to do too it looks like so for me the price will be a sixer and 8 AC Delco plugs, at 92k now so I'll be doing it soon, slight shudder at idle currently.

Trans service (if never done before) & throttle-body cleaning if not done anytime after 50,000 miles. Consider cooling system service if never done.

The book says change the coolant every 5 years. I realize the NorthStar engine's head gaskets are a thing of the past, or supposed to be, but I change the fluid every two years. Cheap insurance.[COLOR="Silver"]

Can someone please provide the Plugs ID, For the 2006 STS RWD,Northstar 1SF above.
or Part number, name of Mfg (DELCO) ?, etc.
Do you think we can get them at Autozone, O-Reillys, Advance, etc.?
vice/Cadillac dealers.....
Mine's due soon, but NOT tomorrow.
Are they $ 10.00 apiece ? :cool2::cool::cool2:
thanks

P.S. Cadillac dealer, change engine coolant, about $ 130.00
Cadillac dealer, change transmission fluid, about $ 240.00

Depends on year. Not sure why but the 04-06 lh2 has a different gap than the 07+ thus different plugs.

04-06 sounds like a DTS Spec. Those N* were not redesigned as were the the 05 & up STS. I'd check your owners manual.

Check the plug numbers. No part stores stocks delcos for 04-06 but they hve them 07+. Different gap. No clue why.

I wonder what my dealer would put in.

Calling Rippy's Chris Heath - If you see this, what would you source if I asked for plugs for my 2006?
