The 93-95 EGR valve is difficult to remove but you don't have to pull the engine. As Phill suggests, you need to disconnect the engine mounts and jack up the right side of the engine.

You cannot diagnose DTC32 w/o a TECH1, Mastertech or TECH2. .

But, before you do all that work, if you don't own a T1, Mastertech or a T2, I'd take the car to a shop that does and have them troubleshoot the EGR with a tester. That way you'll know for sure if you need to replace the valve before you go to the trouble to lift up the engine.
