Well cruising around today I noticed the CEL come on and went to the nearby AutoZone. The guys pulled the code reader out and got a P013E code "Delayed Response Rich to Lean sensor 2". Based on what I have read so far it sounds like the #2 O2 sensor may be bad or I may have a cracked down pipe? Can anyone offer and advise? Thanks

 

Look at the flex pipe. Especially if it is louder than it used to be.
