Re: '99 Seville STS
Read the sticky thread at the top of the page down in Cadillac technical Discussion, Technical Tips: How to pull codes on.........and later Seville/Deville. When you pull your first codes, write them down but don't clear them. Use the links to decipher each code and come back here.

If you get P0335/6, P0385/6, and maybe P0300 you have a CKP (CranKshaft Position sensor) fault. www.rockauto.com or www.gmotors.com, $110 in parts (get both sensors) and a couple of your hours on your back. Not fun, but do-able.
