Are you sure you put the hoses on the right ports on the sensor? Does either hose have a hole in it? Have you checked for a good ground on the harness?
Does your EGR valve operate (hold vacuum, open and close smoothly) as it should?

Still unsure why he won't use his skylardog username. I won't be helping someone trying to hide behind a username. Own up to your original mistakes and move on with life. You won't go far in life without accountability
