My 250 Started running rough just before winter and the "check engine" light came on. I went to Auto Zone and the code read "misfire on cylinder #2". I figured this would be a easy fix once it gets warms so I put her away for winter.
Fast-forward to now.
I Changed all the plugs (they were due) and re-set the codes. Well she started missing and running rough at idle and it said "misfire on cylinder #2" again.
Next: I swapped coil packs between 1 & 2, assuming if it was the coil pack the problem would move to cylinder 1. After a short amount of time driving the code tripped again and said "misfire on cylinder #2".
Next: Last night I swapped my fuel injectors between # 1 & 2, but the code tripped again and says "misfire on cylinder #2".
I'm out of ideas ...
Any help would be great..
