Probably going to be an MAF issue. Mine started with just a 0170, then 0170, 0173, etc. Cleaning the MAF and resetting the code helped for a while, but the fault codes came back every couple of months. Finally replaced the MAF, all is good for over a year now.

don't mean to steal this thread.
Hi Greg, how hard was it to get to the 2 front O2 sensors?
Did you use OEM O2 sensors or the universal 4 wire sensors?
If you used the universal 4 wire sensors, which ones, any issues?
I have 2 codes pending P0130, P0150, probably got to take care of that soon.
