I've had this Mitsubishi for a little over a year and lately in the cold it hasn't wanted to start/run very well. I replaced the oil pressure sensor, plugs, and drained the vaporizer so far. If it starts up and I give it fuel in neutral it will idol all the way up, however, if its in forward of reverse it doesn't want to go over a 1 mph and it wont lift more than a couple hundred pounds without bogging down. the low propane light also stays on right after I replace the tank, so i don't know if its a fuel consumption issue or vaporizer or both.
