I would try dismantling it & clean it out first, at that price you have nothing to loose.

are you thinking about leaving the EGR off all together?

perhaps block it with a blanking plate, but it could still throw up an ecu fault as the VSV (vacuum Solinoid Valve) may detect erratic operation due to the blocking of the EGR. The VSV controls the EGR by sucking/blowing air through a tube to the EGR where it pulls/puches the valve to open/close with instructions from the ECU.
A common prob with these models are the VSV valves clogging up underneath, there is a paper type filter about the size of a 20c piece which clogs up with dirt/mud etc and the VSV doesnt operarate correctly. But it still could also be a sticky EGR? process of elimination. as suggested giving it a clean could help things.

The later rodeos came with a revised VSV which has a 3rd tube going to the air-box to get clean air, eliminating the need for the paper filter.
have looked around for a EGR for myself, $200 is not a bad price.

let us know how you go.
