Hello,
My Mustang is a 2013 V8 with track pack (52 000 miles), it is stock except we have a doubt on the crankshaft.
It rumbles a little at idle.

Once in a while I have a DTC for misfire on cylinder 1 and 3, one week later i have a DTC with misfire on cylinder 2 and 4.
2 weeks later same thing, misfire on cylinder 1 and 3 than on cylinder 2 and 4
The DTC appears, i feel a problem of power few seconds and then it comes back to normal and DTC disappears. This happen when i am above 4500...
