I have the dreaded code and have read every thread I could find on this. I have already removed the intake and cleaned out all of the passages and replaced all of the hoses. Next I replaced the EGR modulator, VSV and EGR, as well as testing the temperature sensor trying to track it down. Now I am at a loss, I hate throwing money at this thing, but now I don't even know anyplace else to throw money at. The real bummer of this is that I have to get it smogged so that I can renew my registration and I can't get the darn check enginge light off. Please help!
