I recently purchased a 2000 DTS w/ 51000 miles. I have been experiencing a rough idle; when I brought the car to a Caddy dealer, he stated the engine was running fine and no codes were found. He further stated "a rough idle was typical for a Northstar engine." Does anyone else have this problem and/or have any remedies?

Thanks in advance.
