Help needed, codes

[Leathalwoman]

Hey there I recently brought a ve sv6 ute and it's coming up with these codes. It goes into limp mode. Clearing the codes and keeping it above 1500 revs and its fine but obv not a fix by any means was enough to drive it home.
The codes are as following
P0030
PO050
PO100
P0113
PO69E

Don't know anything much about the motors above the VS so any help would be greatly appreciated

So looking at those codes looks like 02sensors, and possibly fuel pump? Can I have some advice as to what my next step should he please. Cheers

both upstream O2 sensor heaters not working so first step check power and grounds
fixed up original answer as 2 codes merged
maf sensor
intake air temp
and fuel pump
i would be investigating the ground connections carefully
make sure maf sensor is plugged in

Personal checking and testing,
Above DTC diagnosis codes sounds like a common denominator !

As mentioned/listed above.
