It's not running so rich that it's fouling plugs or anything but there's a distinct (and strong) smell of gas while driving. I will attribute part of that to having turn downs under the trunk instead of tips extending past the bumper but it's still more than there should be I'm sure. That and the fact that I'm using an eighth tank of gas on my short commute to work and back...it has to be running mega rich. I don't have my odometer fixed yet so can't pin down an exact MPG number but it's not good. I used MAF cleaner and it didn't change anything so I'm going to assume it's not that. My coolant temp gauge shows it's running very cold but I'm pretty sure it's just a bad sender because the fan still comes on and the heat blows very hot. I also have an intermittent CEL that I have yet to check. I'm going to start with pulling the codes to see if the computer will actually tell me what's wrong. If not I'll start by checking the TPS calibration. If that's not it I guess it'll be down to changing O2 sensors (but the computer should say if they're bad, right?).
