2-4-1 means that the EGR system's flow is faulty. The EGR is the Exhaust Gas Recirculating system. It recirculates a small amount of the exhaust gas back into the intake reducing emmissions. I would recommend cleaning your flame trap and all the little vacuum hoses connected to the intake and trap. Often they can become clogged. Also, check your EGR Valve mounted on the back of your intake manifold to see if it's clogged. Hopefully one or all of these will cure your ills. If not, then it could even be your catalytic converter not reading the airflow correctly or one or both of your O2 sensors, but most likely it a clogged recirc. hose or hoses, including the flame trap.
