If I remember correctly you said you have a Haynes manual for your car. 
That code information should be in there, probably in the section on 

Just a word of warning.  On our '95 Geo Tracker you have to go through a 
fairly complex diagnostic routine to trouble shoot the EGR system including 
running the car in gear with the rear wheels off the ground.  The EGR code 
may only point you at the EGR system which may be made up of a few 
components that need to be tested out separately.  On the Tracker you only 
had to do this for the '95, the '89 to 94's were much simpler.

I did a quick Google search and came up with this:

Clicking  on the code will give you information on that code.  A 32 code has 
two different routes depending on how your car is equipped
