What is the check engine code that the vehicle is throwing. This will be important to know whats wrong so you can get the cheapest fix.

I put on code scanner and po302 and po401 were the codes

Alright lets worry bout the p0401 code right now. The other code probably came up due to the vehicle running bad with egr hooked up.

I would check the egr exhaust tube and ports in the manifold are clean. Next step wwould be to check the evp or the pfe sensor computer may not be seing enough flow due to bad sensor and pulling egr even more open causing rough running
