Trouble Codes 32 and 103 always appearing together

[dr69]

Do DTC's 32 (EGR malfunction) and 103 (Neutral Position Switch) have ANYTHING to do w/ each other? I don't see a correlation, but when I reset the ECM to erase them (Yes, I know I need to fix them) I can drive for days w/o getting a code, then BAM! when I get the code, it's ALWAYS both of them.

What's the most probable cause for each of these codes? I hate buying and replacing crap I don't need to replace!
