Tune issue? Keep fouling out 02s After my lt install & mail in tune all seemed well. A week later I get 02 codes from the new acdelco sensors I installed. (headers were used not new so wasn't expecting them to foul out) I finally replaced them after no other fix was working. No codes for a day or two but now they're back. Is my tune possibly off? If I get the interface cable and software online can I look and possibly correct what ever might be wrong. Or will I only be able to see/read my cars data / trouble issues. ?

To scan your(I think you have an LT1) car, all you need is a free scanning program and the correct cable and a laptop. It can show you anything the pcm sees in realish time. Youll need something like tunercats to edit anything in the pcm tho.
