Corroded or damaged connector
Reduction in engine performance, especially at low RPM levels
Diminished fuel efficiency

Possible Causes :

Faulty IMRC actuator/sensor
A large vacuum leak would cause a massive amount of un-metered air to enter the intake manifold resulting in an overly lean mixture.
Fuel with a large percentage of sulfur will clog the DPF quickly

Repair Processes :
