Well, I'm currently going throught the P0430 code and i can DEFINITELY say that my gas mileage is affected. I took a trip just before the CEL came on. I managed about 390miles on one tank. Since it's been on, I've taken the same trip and only managed about 300miles/tank =(
I'm going to install my MIL Elminators as soon as I can. (already got them. just don't have a jack yet)
I'll keep you informed on my results!
