The systems that tend to fail first on the 1999 Ford F-150, with the typical mileage window when each becomes a concern. Detailed repair-cost ranges and exact what-to-check inspection notes are in the full report.
On the 5.4L Triton V8 (and less commonly the 4.6L), the cylinder head design with only 4-5 threads for spark plugs can lead to plugs loosening or ejecting, causing misfires and potential cylinder head damage. Repair involves special inse…
