Exhaust Gas RECIRCULATION (EGR) System: Notes

NOTE: Condition of exhaust system can affect EGR system operation. Excessive backpressure caused by exhaust system restrictions may create driveability problems. Exhaust system leaks may decrease backpressure enough to prevent proper EGR operation. Visually inspect exhaust system if leaks are suspected.
