my MPG's have gone down the drain and throttle response is horrible, i have the edge evo 2. the only codes that i can pull are p0472 and p0470, both having to do with the EBV, so i am thinking mine might be stuck about half way, it doesnt make the jet noise like when its cold and im just starting it up but it doesnt sound normal... could this be the ebv sticking or am i crazy? not trying to thread jack, figured same problem and i could bump it up

ya dude. Totally the EBV.

could be bad fuel too. but if it is the ebv you should cut the thing out if you dont live in a realy cold area.
