Quizplus · Accepted Answer

During a four-cylinder cutout test, the minimum number of cylinders that should be firing if all the Electronic Unit Injectors (EUIs) are functioning properly is two. This is because the test involves cutting out one cylinder at a time to assess its performance relative to the others, ensuring at least two cylinders are always operational in a four-cylinder engine setup during the test cycles.
