Three weeks ago i got codes P0130 and P0171. So I changed the 2 front O2 sensors. Two weeks later, same codes. Cleared themselves in a couple of days. Last week CEL came back on with P0130 and P1171. CEL currently still on. Should I change the 2 back O2 sensors as well as the MAF?

 

How is your fuel mileage? Also have you checked your cat. converter?

And why didnt this get posted in your original thread about the same problem?

 

Mileage is normal. Cats seem normal. I re posted because I couldnt get any responces in other thread. Looking to buy parts online (if needed) so I can work on it Fri.
Thanks for your help. PS did you get your A/C problem figured out?
