I just got my RL back from the shop(for the fifth time) and I believe they have finally got it. They reprogramed my cam with the latest disc and I have no lag in shifting from 1st to 2nd like I did. My RL runs stronger than it has ever. It does not have a hard start anymore and does not back fire like Smokey's(Chris Tucker) car on "Friday". Anyone having trouble with their 04 RL starting or running rich than I suggest calling your local Saturn and getting the 2005 disc #13 to fix this problem.
