P0301 code issue and check engine light flashing
2017 F-250 Super Duty 6.2
I keep getting a P0301 or 0300 code from time to time. What could be causing this?
Also I tow a 33' bumper pull camper, when I was towing this past vacation I noticed the check engine light will flash when it down shifts from 4th to 3rd trying to pass, but when I tow with the "haul mode" on it doesn't not come on at all. I was towing up a steep upgrade with it in "haul mode" and it never flashed. Could someone point me in the direction of what my problems could be?

Depending on your mileage but probably a coil pack on cylinder 1 (hence P0301) and the P0300 is for random misfires. You can try servicing it with a ~$10 rebuild kit. New ones are ~$150 each from Motorcraft or Napa
