Pulled The Codes from the 93! Help?!

[Ryannn]

157 - (R,M) Mass Air Flow signal is/was low or grounded - MAF
172- (R,M) Oxygen sensor not switching - system is or was lean - Single, Right or Rear HO2S - Fuel control
176- (M) Oxygen sensor not switching - system is or was lean Left or Front HO2S - Fuel control

Do I just replace all of those? Does it have two 02 Sensors? Whats the deal here?

Sounds like the MAF is bad or dirty,thus causing the lean codes on both banks.

Im getting a New MAF and two new Oxygen sensors tonight so we will see how that goes..

I doubt it is the O2's like I said.

When the MAF readings are shit, you will get lean/rich codes on both banks. You've got lean codes on both banks.

Replace the MAF, disconnect the battery for 10 minutes to reset the KAM and give that a go. Bet your problem is gone.

im with sasquatch, it unlikely both O2 sensors are bad, its probably your MAF

So I got a Reman MAF and a Brand spanking new Optima Deep Cycle Battery today. I disconnect the battery tomorrow.
