I've got a 99' SL. I've been right around the 45-48mpg range since i've bought the car. I've got a vacuum gauge installed and do a lot of EOC, not so much pulse and glide though.

Saturn Shifter Bushing Cable Replacement End Loop | eBay
These saturns are NOTORIOUS for faulty shifter cables. Specifically, connection between the metal cable and the plastic eyelet is a horrible design. The connection is so weak that it breaks very easily. Don't waste your money on buying a new shift cable, because it will do the same thing 2 weeks after you install it (the dorman cables are worse than the OEM ones).
