Truck Check Engine Light Twice With Cylinder 8 Misfire
What the customer reported
The vehicle owner reported a cylinder misfire on the truck, which started when the check engine light came on twice. There were no physical symptoms at the time and the owner asked the shop to check and advise.
What we found and did
The technician found cylinder #8 misfiring during the initial assessment, which was done at no charge. A compression test passed, and the next step noted was swapping injectors, with added labor if a failed injector was confirmed. The team started with a BG GDI / Fuel Injection Cleaning (4 part) at our Lake Wales shop and re-tested, which was noted as overdue by 84,239 miles.
Result
After the cleaning, the notes recorded no misfires at that time.
