There's a fuel pressure regulator on the driver's side fuel rail that can cause idle issues; it's relatively cheap ($30) and very easy to replace. It's a little metal can about the size of a walnut with a vacume line attached. De-pressurize the fuel rail (using the schrader valve on the passenger side rail) before you remove it.

I just swapped the pump in my '99 silverado as a preventative measure. It was a royal PITA.
Spend a couple of bucks and get the Delphi pump; it'll last you another 9 or 10 years. I've heard some of the cheaper aftermarket pumps failing after less than a year.
