Any codes in the computer? Also have you tried unplugging the egr to see if the problem goes away?

I think that it happens so quick and short period of time that the computer doesn't perceive it is a critical error, because I don't have a check engine light, the only one I have had was a loose gas cap.

I have seen bad egrs not set codes and have symptoms like that. That's why I asked if you tried to unplug the egr valve to see if the problem goes away.
