I have a 2014 Town and Country that has been at garage for 5 weeks now. It has a misfire issue on cylinder#2 at low idle (under 800RPM) Mechanic is stumped by this issue, as he states mechanically there is nothing wrong with this cylinder.

  • Sparkplug ok
  • Coil ok
  • Injector ok
  • wire from injector to ECU ok
  • replaced ECU with chrysler OEM ECU. This helped with misfire but did not completely resolve it.
  • He says valves and rocker arms are fine.
  • fuel spray from injector ok
  • wet and dry compression test ok
  • No signs of a head gasket leak

I have been using this guy for 20years and trust him. He is at a loss what can be causing this misfire on cylinder#2

Any one run into this type of issue and did you ever get resolution

  • Could it have got a bad batch of fuel?

    Can you feel the misfire, or is it the ecu telling you there is a misfire?
