Okey, I'm familour with what the EGR valve is etc. It's at the front of the engine right? Could this be causing my problem? we have checked all the vaccume lines and they are all solid etc.. we have replaced the map sensor we have replaced the TPS sensor and the IAC sensor...

What else could be causing it to idle high until I come to a complete stop? very frustrating...

how much is a block off for the egr? Where can i get it?

any idea's about any of this would be great!! :)
