The replacement egr was bought at autozone part #EGR1044 both ports are clean and the egr was installed in correct position, could the evap system be causing CEL to keep coming back

That's a good way to see if the ports are clogged. But if they are clogged that won clean them When you did that did the engine race and you heard a loud exhaust leak? You don't want to over look that and waste a bunch of time looking at things that aren't the problem.
