Hi, dsalvetti. I just saw your post -
The EFI fuse is located in the engine compartment fuse box - you can't miss it. By resetting - I simply mean that I pulled the fuse for a half a minute and reseated it - I've done this before to help clear OBD II trouble codes. Probably not really applicable in my case, but I did it anyway.

I threw in some valvoline fuel system cleaner, and have slowed down a bit <img src="/forums/images/graemlins/evil.gif" alt="" /> on my last long distance drive - MPG a touch higher 17.6 - but still not where I was at before. Looking to change the fuel filter next. Hopefully it's just the winter gas.
