So I have a BBK O/R X, with MIL eliminators. I was getting a code P0430- Bank 2 lean condition. I thought it was a bad MIL eliminator or I switched them to opposite banks and cleared the code. I'm still getting the P0430 so I guess it isn't the MIL. Where should I start looking for the problem? Could the O2 sensor be bad? And I though I read somewhere that it may be an exhaust leak. Any suggestions? Thanks a lot for your help.
