1997 Plymouth Voyager 3.0L Misfire, Poor Fuel Economy
This van was given to me, and I use it for my business. Runs well but gets poor fuel economy. Seems to misfire under cruse conditions. I obtained these rather odd codes from a new scan tool, the Maxidas, 071C, 071D, 071E, 071F, 0720, 0721, 0722, 0723 described...
