A running compression test indicates a possible restriction on the intake side of a cylinder. what should the technician do next?

I think the technician should inspect the suspect components. A compression test is a method used to establish the compressive force or crush resistance of a material and the ability of the material to recover after specified compressive force is applied and even held over a defined period of time. The test reveals the condition of the engine's valves, its valve seats, and piston rings and whether these parts are wearing evenly.
