If my memory serves me correct, I was getting the P0351 from my MSD box.
You didnt list that as one of your mods though.
This code is like a soft code. It wont set off the MIL by itself. When the other code was thrown and you checked on it, both codes were showing. You probably had the 0351 code for a long time and didnt even know it. I have been running around for like 4 years with that code and it doesnt affect anything.
The other code, I dont have experience with but it seems like a code for a a shorted or burned wire for an o2 sensor or just a bad sensor. If you have access to a scan tool with a live display, you can track it down quite easily.

Hope this is some help to you.
