Just did a scan on my 92x -- 11 or 111s is pass (good) - 536 code because you may not have floored the gas pedal during a particular part of the koeo test (i forgot to do that too) - 157 (maf sensor) - the codes are in the haynes manual chap 6

ya my bad the maf is low voltage is that a problem with maf or power wire going to it?

correction nugs: 536 is Brake ON/OFF (BOO) circuit failure/not activateed during the KOER test

i thought about it and i had started the truck with the maf harness disconnected once (157), and my brake\hazard fuse had blown on me (536). I cleared the codes by pulling the wire during the test, drove the truck and reran test, all 11s and 111s. thanks for the help docksider!
