Been having problems with my car since about 2 days ago, it has a rough idle, and when I give it hard gas it feels as if I'm pulling a dang boat. It has not cats, and I had an auto parts store read it for codes, it threw two codes, 1st bank was some sort of emissions, 2nd bank said my cats were all jacked up. So I have no idea what's going on. I have had thoughts of it being the plugs or COPs. Cause it would act normal at high rpm. But like I said I've found a small exhaust leak near the rear.

Exhaust leak probably wouldnt call that. Like you said, check the plugs make sure nothing is fouled up. Also give your PCV valve a check too. If it's clogged or collapsed you'll lose a ton of power.

Wait, does it have cats or no and if no do you have the downstream o2s disabled?

Need to list the actual codes, lets start there.
