Just got my LTs on...no codes??
I did the !EGR, !AIR, and I do not have my rear O2 sensors plugged in (will be getting an ORY anyway). The only code I have gotten was for the EGR low flow, but I had this before with the manifolds.
Shouldnt the O2 codes pop up right away?? Or does that require a 'drive cycle'?
