Well I went on vacation. The whole way out, the torque converter never locked up once. 80 mph at 2700 rpm, getting 11mpg. I was frustrated, to say the least. It kicked in and out while driving around and seemed like something had been stuck and was starting to operate normally. I keep getting an active code for p0300 misfire. I cleared the code and the torque converter locked up immediately. So the trans works as it should. But I'm still only getting 12 mpg on the interstate, and I don't understand why. It's so frustrating.
