Colorado EGR issues

Hi Guys
A few weekends ago the following happened to my 2008 Colorado 3L TD
Saturday - Replaced exhaust with 3" all the way, high flow muffler, no cat
Sunday -
Drove for 100k, past a truck bit of wind force shook the car abit, and cruise control stopped working, drove for another 50k then pulled over turned engine off, started back up and got an engine light
Today got a scanner and im getting the following error "EGR circuit flow malfunction" or something similar
Is the problem due to the new exhaust?
Hoping its a case of the wind force has pulled something off, but I cant seem to find anything.
