Loaded it, sounds good but 2 codes P1000 OBD system readiness rest not complete
P2196 02 Sensor signal stuck rich bank 1

Lift both at
MAF
stay both above 25 to 28
In idle after 10 min warm up

But when I load the 91 JLT tune with +5 MAF it works okay. Just my short trim fuels are at 15 at idle. How so i adjust that? The file is above
