I also have been experiencing the same problem with my 1999 Silverado. Light came on about a week ago. I took it to the dealer and forked out 270.00 for a fuel injection service. Light was off for two days and just came back on yesterday. I took it to AutoZone and they hooked it up the the computer and got the reading that banks one and two were burning lean, which is the same thing the dealer told me. Dealer wants me to bring it back in, but I don't want to go back and forth with them while they try to figure out what went wrong. Rushingm any updates on how your's is running since replacing the ERG valve?
