Just read your "engine runs rough or misfires" article; very informative. My vehicle has these symptoms more often when the outside temp is warmer and/or during long distances. Low fuel level tends to amplify the problems also. Occasionally when I accelerate quickly the vehicle revs but doesn't seem to be able to get into gear and/or revs too high before up-shifting. This is fairly uncommon but the low power, jerking & sputtering during acceleration have become almost daily occurrences. Throwing a code but I cannot remember what it is: something to do with a possible O2 sensor & it was coming from only one of the banks. Sounds like I'm insane but believe me, I am very good at paying attention to intermittent issues in order to provide information to repair them. Please help!!
