Ignition system component failure is the most common cause when this code is stored in the PCM. Ignition system components, including spark plugs, plug wires and boots, and ignition coils are most often the culprit but beware of other causes, as well. These include lean conditions caused by insufficient fuel pressure, excessive engine vacuum leak/s, EGR system malfunction, clogged catalytic converter/s, or faulty fuel injectors. How do you troubleshoot P0311 ? Pack the connector cavity with dielectric silicone compound (same stuff they use for light bulb sockets and spark plug wires) and reassemble. With the valve disconnected, the red voltmeter lead should be attached to the IMRC valve power wire and the black voltmeter lead connected to ground.
