Dear Sir,
The EGR system of my 1300cc Statin Wagon worked well upto date. I have noticed poor acceleration/heavy knocking/rough idle/difficult starting and sudden engine cut-off at times.The thick rubber hose at the bottom of the EGR Vacccum Modulator disconnects when I accelerate.
Is the Catalytic converter blocked?
Kindly advice me the reason for above to educate self before I take take it to a workshop.
Best regards

Leo
