If diagnostics lead to ignition coil replacement, swap the ignition coil(s) between the misfired cylinder and a known good cylinder. Only replace the ignition coil if the misfire concern follows that particular ignition coil. If the misfire condition does not follow the coil, apply dielectric grease to the boot, reinstall the ignition coil in the original cylinder and continue normal diagnostics in Workshop Manual (WSM), Section 303-07C.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2022/MC-10207118-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2022/MC-10207118-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10207118","components":[{"id":"electrical","name":"Electrical system","parent":null},{"id":"engine","name":"Engine","parent":null},{"id":"ignition","name":"Ignition","parent":"electrical"}],"codes":[],"topics":[],"vehicles":[{"make":"FORD","model":"F-150","year_from":2021,"year_to":2022,"match":"exact","vehicle_ids":["2021_ford_f-150","2022_ford_f-150"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
