Fuel Trim Imbalance Case Study, presented by John Thornton

Within this fuel trim imbalance case study, John diagnoses an 07 Ford F150 5.4L that misfires badly to the point where it stalls at idle. This is one of many case studies from our “Diagnosing Fuel Related Driveability problems with Scan Data” video. The full video can be found here:
