It has codes! scan it again these engine are always doing something.."No codes no check engine light.Ones give a code for rich on bank 1 or 2."? seems like a code what ever, The Check engine light doesn't have to be ON read the Data off the computer and its and easy fix. Check the long term and short term /fuel trims and throttle body. You REALLY, haven't found a mechanic yet. This stuff is so easy. Regards

I Have A 07’ Yukon SLT. And I been Having battery drainage problems lately.. it will be working Fine than one minute I while get back in it to drive and it will be Dead! Get a jump, it comes back on and be fine for weeks than one day it just dies again? Not sure what’s wrong? But what I did find out is that the owner before me had Speakers hooked up and the loose Wirer's are still running under my seats and in my truck the other end of the wiRers that ran to the speaker is just thier live wirers with nothing hooked to it? Could that possibly be why the battery is seen tobe draining and if So what could I do to fix it, or either how could I disconnect the wirers from the battery running live under my seats??? 4 Answers
