Hey Y'all,

I have a 1999 Chevy Silverado with a 5.3L V8. Roughly 2 weeks ago my check engine light came on, i grabbed the scanner from work and threw it on my truck. I cleared the codes and it just came back on when I was on my home. The scanner told me that bank 1 and bank 2 were both running lean, although I bought the truck back in February with a whole new exhaust on it including all the o2 sensors. I am thinking this issue might be caused by a evap problem some where? If any one has any ideas please let me know.


Thanks
