- Hi Scotty, I own a 2013 Dodge Charger with 190k miles. During March all the way to late October the car runs perfect, but as soon as winter comes (cold times) the check engine pops out with the codes P0300, P0301, P0303, & P0305. I already changed the spark plugs, the coils and tested the fuel injector and they are working fine. Also when you turn the car on (either on winter or summer) you can feel a small misfire around 1000rpm and then goes away.

Does it have the hemi or the pentastar?
It’s a v6 3.6L

Those years are plagues with camshaft/rocker arm failure and cylinder head failure. Remove the valve cover and inspect for worn out camshaft from seized rocker arm bearings. Perform cylinder leak down test and make sure they cylinders are holding pressure.

Scotty actually reviewed a high mileage hemi and it had same issues as Mopartech says.
