P1176
17584
"Bank 1 oxygen sensor correction behind catalytic converter, Control limit reached
- Check oxygen sensor aging, oxygen sensor before catalytic converter"
A bit ambiguous (lifted directly from Bentley)... is it the pre cat or post cat sensor?
Ok, I get it now: when the front sensor craps out the ECU turns control over to the rear sensor... this code says the rear reached it's limit trying to correct for the failing front Ox sensor.
In any case it looks like a bad Ox sensor and typically you change 'em both anyway...
That's what I'd recommend...

so you think its got nothing to do with the maf?
Heh! well, not necessarily... the first maf specific code my car "threw" took a maf AND a new pre-cat ox sensor to resolve.
More recently: a drivability problem (hesitations) with no codes:
the first new MAF.. no change
a second new MAF.. way better
(both were "remans" from ECS Tuning)
sorry this is less than helpful... codes and repairing these cars is not a precise science

best deal?
there's been a "run up" on the ox sensor's pricing recently... best bet: try a search on this forum...
reman MAFs are fine: it's a new sensor combined with a recycled holder

where is the pre-cat sensor? it's accessable from above ->

assuming a 225, remove the charge pipe (larger arrow) to gain access... the sensor is behind the cylinder head, below the pipe, it's connector is supported by a bracket attached to the firewall...

If you do need to try a MAF, I recall interchangeability problems with some 180's... verify your engine code (the three letters stamped in the front of the cylinder head) against the MAF's part number... a "reman" may not work...
There are lots of knowledgable 180 owners on the forum, you might try another post asking for their input re the correct MAF
