Question

Quizplus · Accepted Answer

Technician A is correct because a cylinder performance test, also known as a power balance test, is specifically designed to identify which cylinder is misfiring by measuring the contribution of each cylinder to the engine's power output. A vacuum gauge is not typically used to pinpoint a specific misfiring cylinder.
