Ok on the p0171 code, did a little research, I wasn't wrong for buying a fuel filter, but that code could also mean lots of other things need to be looked at too. So swapped the used filter AutoZone sold me, but haven't put it in yet, got the little $10 plastic tool to remove the filter line clips properly, but per that code, still need to check for vacuum leaks, O2 sensor problem, etc. What the code literally means is that the top O2 sensor is picking up too much oxygen. So, my cat could be bad too, one part at a time. We'll see.
