Sorry for posting something that i am sure has been done to death, but i cant find enough to answer my questions, so here goes....
I am giving my 2005 2.2 Direct Sri a service and thought i would quickly whip off the throttle body to give it a clean. I was expecting a bit of gunk on there but i was surprised at just how much there was. I have cleaned it all up inc the tube that sits in the manifold but looking down into it there is a ton of gunk in there too which i am not going to attempt to do anything about just now. Might take the manifold off at some point for a clean through with some petrol though.
So the questions now....having a read a bit it appears that fitting an EGR mod will reduce the build up of gunk on the throttle body etc....can anyone tell me how to do this on my YH engine....read something about a bit of coke can??
Car has done 41K miles....definitely running a bit smoother with the throttle body cleaned....picks up better from idle too
