codes, codes and more codes!
 

well im thinking its either an O2 sensor of MAF.....input?

I would look into the bank two, upstream o2 sensor. Those codes are all related to that sensor. You may want to just replace it and see what happens. Looks to me like it's probably dead. You could take a look at the wiring first, just to be sure it's not melted to the exhaust or something like that.
It's not likely to have anything to do with the maf. That will normally effect both banks.

sounds good, i will get one on order. thanks!

I've been able to fix "too lean" codes by finding vacuum leaks and reattaching or clamping vacuum hoses. Most were in SAI system and used small cable ties to clamp because they are easily knocked off doing other maintenance.

Since your 02 code is also fuel ratio related you may want to check for vacuum leaks first.

From D2 manual:
......

Not sure if your reader can show Fuel Trims but this is very helpful in diagnosis.

This is true

Just to reiterate, don't go out an buy an oxygen sensor until checking for vacuum leaks, which are more common than a faulty sensor.

A vacuum leak or low fuel pressure can occasionally give you lean codes on one bank. However, both of those problems should give lean codes for both banks. If you have a scan tool with live data, have a look at the fuel trims. If they are both around +20 or +25% then go after fuel or vacuum leaks. Sounds to me like a bad o2 sensor or wiring.

I had the 1172 code, I had a vacuum leak on the left side of the upper intake manifold. I would listen for any hissing noises when under the hood. That's all the help I am able to provide though, good luck.

A Scangauge II will give you live readings of your oxygen sensors. I imagine many other scanners will as well. Output should continuously vary from 0 to 1 volt. Easy to tell if you need a new sensor (or new wiring.)
