weird chugging

[ProfGlenn]

Hi - I have a 1.8 Auris Hybrid.  Tonight as I pulled away from the traffic lights there was one big chugg.  Then fine.  Happened three times in a row at three sets of lights.  The car was not cold.  Then a faint smell of fuel.  Then all seemed fine.  Any ideas?  Thanks, Glenn

How much miles on the car? On the PriusChat there is many reports that >150k miles EGR system starts to block out and needs to be cleaned or replaced. EGR system parts: cooler, valve, pipe ftom valveto intage manifold, then small egr passages on intage manifold.

Rough starting, lowspeed are reported for example when EGR is blocked.

Hi - that was a different chugging.  That was more like the car was trying to throw up.  This time it's a gentle chugg pulling away from stationary.
