I’ve got the symptoms of a vacuum leak; aka high idle and no power. The car is idling at 1500 to 2000 rpm. Could the EGR cause this problem? I can not find any vacuum leaks, and the EGR is the only component that I haven’t changed yet.

I own an Ashok Leyland EGR system 1618T. I have changed the EGR three times, and again it is defective. This is the fourth time. The EGR is leaking from inside. What are the possible causes?
