just had a zafira turn up , 2003 z18xe . running like a bag and no power . have pulled - p0170 mixture lean , p0100 maas/vol airflow sensor circuit low input , p0130 02 sensor incorrect signal and p0130 02 sensor 1 circuit voltage low .

had both 02s sitting at 20mv and not switching and well down on power with mass v ranging from 0.35 to 0.77 on tickover and around 9 kgh .

fitted new air flow meter (fuel parts) and now car drives fine with normal power and ticks over smooth but both 02s are sitting around 960mv now saying rich and both heaters saying on . mass v are around 0.39 to 0.80 and 11/12 kgh on tick over .

now have p0170 mixture rich  and p0130 02 sensor 1 incorrect signal

is this due to a non oem air flow meter being fitted ? cant find any air leaks or exhaust blows

Did you clear the adaptations after fitting the airmass sensor?
When not you should be able to clear them with EOBD/OBD2 by clearing the fault codes.

If you read the Long Term Fuel Trim with EOBD/OBD2, what is its value?

Short term is trying to lean the mixture but is at the limit.
However Long term fuel trim is making the mixture Richer by 15%? Or did you forget the minus sign?
Try clearing the fuel trims and then confirm it's on zero before the test drive.
Otherwise it looks like a very strange output from the MAF-sensor.
