Christopher,
Just for input here, I replaced my O2 Sensor this summer, it was never
changed and had about 100,000 miles on it. It was nasty to say the least.
Also, I got a Code 32(EGR Valve), so I pulled the EGR vavle off my Dak and
it appears that there is an electrical connector coming off the EGR Valve.
Within this connector one of the prongs had broken off, causing a fault code
to appear. The valve was not cheap, at $80(came with a new gasket). Might
want to try replacing your o2 sensor and looking at the EGR valve before
thinking the puter is bad.
