91 z28 codes 32&33 won't go away

My 91 z has codes 32 and 33. Last weekend I tried to fix this by replacing my egr valve an MAP sensor. Unfortunatley I am still lighting up the SES. All of my vacuum connections seem ok. The only thing I was thinking I might need is a new vacuum solenoid. Does anyone have any Ideas for me ?
