I haven't looked up the code 32 yet, but on your EGR valve there should
be a little "heat sensor".  If the ECM commands EGR and this sensor doesn't
pick-up any heat - then it thinks that the EGR valve isn't working...

Accel makes a block-off plate for their intake manifolds that could
be used to block off the EGR valve if you want to remove it.  Then
just drill and tap a hole for this heat switch into the block off
plate on the hot(exhaust side) and plug the vaccuum line from the 
EGR solenoid.  Of course, this isn't emissions legal at all...
I don't know if Accel offers this block-off plate for sell separately.

good luck,

T.
