Trouble Code 32 on My S-10 Blazer........

After driving about 10 or 15 miles my Service Engine Light comes on. I have had the codes checked and it came up 32 which is the EGR valve but after repacing the EGR Valve and resetting by disconnecting the battery, the light came on again......Any idea's?

Thanks, Marla

there could be build up in the egr tubes blocking exhaust flow, or the vacum line may have a crack which would not open the valve at all.
