With automatic mixture control EGR parts stay quite a bit cleaner than they used to. I remember the days when you could cake up half inch diameter pipes solid as a rock with carbon.

Probably DPFE sensor, especially if the very short stub hosed one. I had to make up a workaround on mine when water kept getting into sensor to fault it.
