I had the "engine" light come on about 6 months ago. I had Autozone check the code. It came up "EGR valve insufficiant flow" or something close to that. I bought an EGR vavle factory direct off of ebay and put it in. I cleared the code (disconnect battery). But after driving a few miles the light came back on. I had Autozone check it again and it came back the same. What am I missing? It is just a plug and 2 bolts.

You need to check all the possible connections to the EGR...maybe it's not an EGR but a hose, or some other part that is blocking the flow

Another waste of time from Autozone.

Super common problem. how much did you pay for that valve on ebay? It's only $65 list from the dealer.

V6 or 4 cylinder. how many miles?
V6s have an extended EGR warranty. They may be out by now though.
either are subject to port clogging

On V6s the egr valve must be pulled, and the upper intake removed.
There are ports both in the upper intake and the lower that need to be cleaned out. There is also an "update kit" that includes a sleeve type tube to install in the intake, which requires drilling out the upper intake.

On 4 cylinder engines, the upper half of the intake manifold (plenum) has to be removed and there is a small round port that plugs up that needs to be carefully cleaned out.
