Constructed with adjustable probes and two screw-on adapters for varying diameters, this universal noid light identifies pulse issues in throttle body, ported, and sequential central port fuel injection systems. A built-in suction cup secures the tool to the windshield or vehicle body, enabling a single operator to view the flashing light indicator from the front seat while cranking the ignition. A flashing light indicates normal pulses, while a constant light or no light signals a system problem.
