jdraupp, if I may jump in here, you should replace all the O2 sensors at the same time because it makes the computer go haywire when one is dull and the other is clean and super-sensitive.

When I read the code numbers on your thread title I instantly thought oxygen sensors.... had the same issue about two years after buying my car.

When the sensors are going out, the computer can get confused and tell you it's a fouled MAF or something else. My tech smiled when he hooked up a PST tool to my car... he turned to me and said, "The car is lying to us. My bet is that it's not the MAF, but an O2 sensor. Replace all four and I bet it will clear it up and you'll get a lot better performance out of the motor as well.

JFP may have better or different advice.
