Backfiring and bogging down

I have a 94 z28 with a 6 speed, lt1. Has a lt4 cam headers and cai, I did not put this on. For the question, when the car heats up and I punch on the gas it does like a skipping and bogging down type deal. I never worked on fuel injection so thats why im here. The closest thing I can compare it too, is when you run really lean on a carbed 350. And it only does this when it approaches, 210 degrees.
