I have a 1998 GMC K1500 suburban. I routinely check my ODB2 scanner and came across fault codes P0131, P0137, P0151 and and P0157. Any suggestions on what causes theme and how to resolve these.

well it runs okay I'd leave it alone those are oxygen sensor fault problems which can be the sensors can be the wiring can be the engine not running correctly can even be the fuel pump not putting out enough pressure they are relatively generic codes and on something that old if it runs good enough most guys will live with it

OBD-CODES.com is an excellent website for looking up codes.
They list possible causes, solutions etc.
