Hey all, I have a tricky one here... i can't find anything that anyone has posted that resembles what I have going on. My car is drinking a ton of gas. I mean a ton. I get about 14-15 mpg, and I'm on the freeway mostly. I just got my exhaust and dp done, and I was thinking that it might be my ancient o2 sensor, so i changed that out, but it hasn't seemed to help. I also have a brand spankin new set of iridiums in, and a new set of moroso wires to go in. My car stinks like unburnt fuel when it's running, and every time I start it there's a plume of white smoke, but it doesn't smell like coolant (for all you harbingers of the bhg!). It runs fine, other than the occasional fuel cut code. The only thing I can come up with is that whenever I hit FC, I get a simultaneous code 31, which is for the AFM... if my afm was going bad, could it be telling my car to dump fuel? Is there anything else that clues you gurus off? It's making me crazy, not to mention raping my pocketbook!
