i did the O2 sensor already!! the only other thing that i haven't changed is the cam sensor. if this works than i'll just drive it til the snow comes. Sean has tempted me into getting his MAF-less system as he's going to an XFI system. it's a little complicated (for me anyway) to jump into this late in the year, but it'll be fun for next year - assuming my wife doesn't find out...LOL!!
