At idle it runs fine, give a little gas and wants to stall. Spits and sputters and has no horse power. Have redone exhaust. Cut catalytic converter out and put new muffler on. Map sensor is new. New fuel pump. New crank sensor. I am lost on what to do next. No codes come up.

It sounds like you have low fuel pressure which will cause the engine run the way you have described.

Here is guide to help you see how to check the fuel pressure if you do not have a gauge you can rent one from the auto parts store for free:
