Using another reader gives me something different.
Expert:  Pete replied 15 days ago.

O.k.,the second image is the code.The first number or reader is incompatible this is why the odd code number shows up.The code you have is for the engine running to rich.This can be caused by a dirty mass air flow sensor needing cleaned or replaced or an issue with the engine air filter dirty or clogged.If these are all checked and found o.k. then this issue can be due to one or more fuel injectors allowing to much fuel into the cylinders causing the rich code to set.

All of these do need checked into to locate and repair the fault.One of these is the cause for the rich fault you have and needs repaired.This noise can be related to the rich running from the engine itself and should go away once the fault is corrected.

If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service,your 5 star rating is appreciated.You can rate at any time and we can continue to work on your question as this will not close out your question.Keep in mind in some cases it can be difficult to fully diagnose or help repair your vehicle without seeing it and I work on delivering the best possible answer from what I see to work with.
