I got one of those wifi dongles that you plug in to the OBD port. It tells me that my runner's got PO125 and PO171 codes, along with the message that my coolant is not warm enough to put the engine management into closed loop mode. It also says that my coolant is at 194˚F, which I believe is correct. And it said that my intake air was 75˚F when the outside temp was about 27˚F. Is that MAF problem or just under-hood air temp? I just did a fuel mileage test and I found that I'm getting 10 mpg in mixed driving. I know that I was told to check the PVC valve and look for vacuum leaks. I didn't do it yet but I'm headed out to the driveway to do that right now. When I looked at the O2 sensors I noticed that the front sensor looks like its been on there for a long time, so long that the nuts that secure it are almost rusted away. Luckily the flange and the studs look ok. The vehicle has 295k miles on the odometer. -- Matt
