Was checking my engine to see how autotap worked, I got a code saying fuel too lean in bank 1 and bank 2, any Idea of what could be wrong when it gives this reading.

 

Did you have a custom chip burned to compensate for the BBK Trottle Body,Granattely Mass Air Flow???

 

I had the same problem: In addistion, it was pinging bad. The solution was 2 fold. 1) There's a TSB for the RH bank. The condensate drain for the AC drains right onto one of the RH O2 sensors. 2) my K&N was contaminating the MAF sensor. My mechanic cleaned it and it hasn't thrown a cosde foro 3 weeks now.

Hope this helps!

Mike was advised of this before shipping and of all the other goodies I bought even the tires was mentioned, let me try what f150tony did, but I have no pinging, just a nice wheezing sound when accelarating.
