6 check engine codes at once?!
All of this at once and I'm wondering wtf.
I noticed that this car has had some exhaust work, a brand new 3 inch mid pipe, brand new flowmaster muffler and brand new echo tips.
I'm wondering how all of this connects together. I have no idea what to do about the fuel injector problem though? Any help would be appreciated.. btw it does seem to idle a little rough but besides that I haven't noticed anything else.
