Why does my uncle's 1998 V6 Toyota 4-Runner misfire at highway speeds? Last month we drove from Los Angeles to Tucson and back, and at what seemed to be random points while we were driving the engine would buck repeatedly. Once it started, it would continue at all speeds, with the engine running particularly rough at low/idle RPM. We took it in to 3 different Toyota dealerships along the way, and to it's home dealership once we got back. They were all happy to service the vehicle, but none were able to fix it and two insisted they couldn't find any problems with the vehicle. [more inside]
