This is an 05 F150 that is having some engine issues going on right now. It’s pretty common for the 5.4 Triton motor to have misfires and blow spark plugs (just due to the engineering of them).
A mistake that people can make is trying to dump money into a car that they later plan on selling. Motor rebuilds or major mechanical fixes can be very costly and end up not being worth it in the long term. In most cases it’s best to save the thousands of dollars in repairs and just cut bait with the car.
In this case unfortunately our customer put too much money into it and didn’t want to keep throwing money into it so they ended up selling it and recouping some of the lost money. A valuable and hard lesson to be had.
