2018 F150 5.0 Approx 7000 miles. Truck runs great but seems to have a curious tendency to develop misfire after not being driven for a while and then taken out in cold temps. Once engine has reached full temp Misfire goes away. This has also been linked to a low battery condition but now I keep trickle charger on battery as truck sometimes sits as long as 2 weeks without going out. Dealer has also experienced the miss while cold and then smooths out when warmed up. Tech had laptop attached the entire time and watched the Misfire disappear. Truck is kept in climate controlled garage which does not go below 55 degrees at night to around 70 during the day.

This has been an off and on condition since the truck was new. I am coming to the conclusion that it just does not like to set for extended periods, then starting after a long sit in the cold seems to make it a little more prevalent at times. Seems like something I will have to live with.

Just wondering if anyone else with the 5.0 has experienced anything like this? Thanks.
