Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.
Is this a code number you are seeing with a code reader plugged into your model?
Let me know so we can continue,thanks Pete.
I apologize as your first replies didnt come through until now.
What scan tool or code reader are you using?What brand and model?
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.
