My check engine light just came on while driving home. I hooked up my OBD II sensor to check the code and said that the system was too rich PO172. I just recently had my timing belt replaced a week an a half ago.

Anyone have any suggestions?

Thanks for the help!

 

Any thoughts?

 

timing could be off, check the timing.

but could be something else like O2 sensor.

 

So you think the timing belt might not be on right?

I also read that it might be my MAF sensor. Would this be related to that?
