Squirrels are mischievous. I learned that the hard way. Tried to start the car (my daily driver, a 2014 Ford Focus) after a 12 hour shift at work. The poor thing had a terrible misfire. I decided to pop the hood to take a peek. That’s when I found this:
See that? That’s a squirrel’s (or other rodent) nest. The wires going to the coil packs on cylinder 2 and 3 are chewed through.
Even the hood insulation has to be replaced. Not sure I want to know what Ford will charge for that
