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.

I had the same errors even after I replaced the MAF. I finally ended up replacing the front Oxygen sensors and now NO MORE ERRORS and the engine runs perfectly 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.
