A Ford F-150 EcoBoost 2.7L V6 with 160,000 miles entered limp mode while towing a 6,500-lb Jayco camper. Three mechanics and a dealership found no fault after the P2099 code cleared when the ignition was cycled. The cause is condensation in the charge air cooler, which, during sudden acceleration on a grade, enters the combustion chambers, causing misfires and triggering a zero-boost limp mode.
