My 2013 Silverado WT with a V6. I have a P2097 and P2099 engine codes. I have replaced the catalytic converter,O2 sensors twice,smoke tested ,fuel pressure tested. Still comes on. Has anyone encountered this,and/or suggestions?

Thanks

 

I am having the same problem. Replaced Sensors, catalytic and still comes on.
Have taken it to 4 shops one beaning the Dealer and no one can it.
What can be done ???
Thanks.

 

Check the MAF sensor. It can throw of the fuel mixture and cause those codes.

 

@Brody103 Respectfully, what is a MAF sensor, and can this pertain to a 2005 Chevy Silverado 1500 LS V-8 as well?

 

@mommafrica Brody hasn't been to the forum in a year and a half so I wouldn't hold my breath for an answer. It's best if you post a new topic with your question , and provide all your vehicle details, and the problem you hare having.

 

LOL!
TYVM for the quick reply.
I will be doing the above once I leave Advance Auto Parts the next day.
