Re: Excessive Fuel Use in Cold Weather

ya the heat problem make shure you have a heat shield, and usaily when exhaust heats up that much, it means it is running lean, but in your case i don't know. Check to make shure it is not leaking any where. And does it sputter any? Hesitate? i would replace the egr valve and the maf sencer they are not that high. I would start with the maf first, it is cheeper.
