To determine if your EGR (Exhaust Gas Recirculation) tube is clogged, look for signs like poor engine performance, increased fuel consumption, rough idling, or the engine light coming on. A clogged EGR tube affects the engine's ability to correctly reroute exhaust gases. Using a diagnostic tool to read error codes can also be very telling. For manual inspection, remove the EGR tube and check for visible carbon build-up. Consider cleaning or replacing the tube if any clog is evident.
