I was driving my RX8 and my check engine light came on. I had been driving it for about 15-20minutes before this happened. My oil pressure and temperature were at normal levels and my car was running normally. I took it to auto zone to see what was wrong and they said that it coded that the target AF feedback system was too lean- right bank. It said that the probable causes could be 1) large vacuum leak, 2) fuel system malfunction, 3) MAF sensor faulty, or 4) ignition system malfunction. My car continues to run fine and all gauges are at their normal levels. We have had much colder weather here than normal. When my light came on the temperature had dropped to 20. Could the temperature be causing my sensors to malfunction? Is this a normal thing? Any info will help. Thanks for any help!

Here is a related thread with the exact same problem.

The simplest and most likely cause is a dirty MAF sensor or intake Air temp. sensor. These can be easily cleaned. Details on how to do this are in the linked thread. I would post further questions in that related thread so others will see your question.
