Hello,

I've watched your show now for about 2 yrs.  I have 2010 honda accord 4 cylinder auto 189,000.   It throwing several codes (see below).   But it drives just fine.   I have always changed engine oil every 10K with Synthetic.  Engine uses 1/2 quart every 5K mile.  I recently changed transmission fluid by doing the drain and fill 3 times with gen. honda auto fluid.  I cleared the codes but now there back with more codes!  I have owned it for 1/2 its life and have driven it normal.   Could I have some sort of Elect.  or ECM problem or is tranny and engine on its last leg?    Note I did replace the Cat about 2 yrs ago.  Long term fuel trim is -4.  Thank for the Help
