09 ss tc

I've been having an issue with my care going into limp mode it's showing p2078 running to rich off idle bank one. I put a new airmass flow and a downstream o2 sensor. Run good for like 25 miles then it when back into limp mode.... I'm thinking maybe my throttle peddle or my throttle position sensor... Any ideas on anything else that could be causing the problem.. I just put a brand new block in it... But the block didn't come with the sensors had to use the old ones
