'97 Tahoe 5.7L running rich

I recently changed the fuel pump in my '97 Tahoe and the
next day the SES light came on. I scanned the trouble
codes from the VCM and it turns out that both banks are
running rich. Chilton manual confirms that the codes
indicate a rich mixture condition.

The problem is that the Chilton manual does not give me
any idea of how to correct the problem.

Anybody seen this and what did you do fix it?

Thanks, Howard
