I have a 2005 Mazda 6 with almost 82k miles on it. yesterday the check engine light turned on the same day I have got the oil change done. I didn't notice any significant difference right away while driving but today I am seeing the car is running slightly rough at idle and sometimes getting a sudden jerk when I accelerate from stop. I don't see difference while running on highway though. I ran to a nearest Autozone shop and checked on the engine codes. They gave me these 4 codes below -
P2915 - Upstream 02 not switching - RF - stuck lean
P2096 - target AF feedback system too lean - right bank
P2177 - Fuel system too lean at off idle- right bank
P0134 - Heated oxygen sensor HO2S (RF) circuit no activity

Guys, what seems to be the issue here? Is it just a coincidental that I had the oil change the same day? I can only take it to dealer next week. Can I drive my car until then? Any inputs and suggestions on the problem are greatly appreciated.
Thanks in advance!

 

I had some engine lights on either my old 4 cy or current v6. After replaced the fuel pump, the engine light on never see again. For v6, fuel pump is not cheap. for 4 cy, I think the price is much cheaper.

 

Did you get your car diagnosed and repaired? I recently had a CEL and I forget what the code was, but it was "fuel system too lean - bank 1". Well I just happened to take a peek under the hood and lo and behold - my air intake hose is finished. I temporarily fixed it by taping it up (should be getting a new hose by tomorrow) and that seems to have solved the issue. So check to see if there are any vacuum leaks.

 

Sounds like a vaccuum leak and possibly something else.
Things I would do: check for vaccuum leaks (if it's PCV hose, change PCV valve also), Clean your MAF and throttle body (reset ECU by unplugging negative terminal for 15 minutes while you clean it, all parts must be dry before restarting, let idle for 15 minutes).
O2 sensor may not be working-----this is more expensive: do later. Do simple things first.

 

Any Updates?
