I'm new to the board, and I have a question about tunning up. I've got a 1999 SLS with almost 56,000 miles. A little about me and the car. I've always wanted an STS or SLS, just love the body style with perforamnce. I recently purchased this 1999 seville SLS with 53,000 miles, 2005 Deville chrome wheels, Fake rag top. The car was EXTREMELY well taken care of and It runs like a champ. But seems to have a little sputter at idle and always takes an extra second to start. I like a car/truck to start by almost breathing on the key if you know what I mean. Anyways...
New fuel filter
and what else?
Also, I've purchased new wheels for my SLS and I'm going to be selling MINT 2005 Deville chrome wheels if anyones interested.
Have you pulled the codes?
If you want to get a baseline future maintenance, drain and change the coolant and sealant. You could change the tranny fluid but if it looks and smells okay, it may be a waste of time.
Don't forget an air filter for you tuneup parts list. I'd wait on the plugs and wires until you do the other items. 56K isn't enough wear on them.
Sorry they Are 16" wheels...I'll take a picture of them if you like and email..
Story on wheels is previous owner had some nice chrome wheels he took and put on the new 2005 deville. The deville had Chrome 16" wheels and put them on "My" SLS. They are nice wheels, Mint condition but I don't feel they fit the car right,.. so I'm purchasing new 5 spoke chrome wheels.
Well I bought the car from a certified caddy dealer who changed the air filter, and trans. fluid, and flushed the radiator coolent already... and no codes are listed.
I don't suppose you can confirm that they added sealant pellets or powder to the cooling system? I get real nervous when in doubt regarding something important like this.
Maybe a few WOTs will clear up the sputter.

Re: Tune Up
Sealant tabs are to prevent leaks from porous casting or imperfect gasket surfaces. THey will not prevent nor cure a bad head gasket. You want "HDC" or 2 tubes of "G12BP" (powdered version of HDC). http://www.barsproducts.com/origin.html
Check the fuel pressure regulator for the sputter. It is on the rear, drivers side, of the intake manifold and has a vacuum line running to it. Take off the vacuum line while it is running and see if any gas comes out . Let it run a minute or two. There should be no gas or fumes.
