Rough Idle Issue 5.4L Ford F150 - This video is the best I can find demonstrating the issue. I have had my 2010 F150 for years and this problem persists. It has never been diagnosed because the dealership could not identify the problem without it actually happening while in their possession. I have invested a lot of money into the purchase of this truck and very upset that Ford has not solved this issue.
Approximately a month ago my truck engine began running rough and the gas mileage began to drop from 16.9 to 15.2. The dealership did a fuel flush, replaced all spark plugs and replaced the #8 injector. Problem persists.
