Shuttering / Quivering on Acceleration / Failing EGR Function Test or NOx Test
SYMPTOM
The car "quivers" under acceleration when the EGR valve first opens. This is more noticeable on the automatics. Note that the car has to be hot and above 1800 RPM for the EGR to operate.
The car might not have any driveablilty symptoms, but will fail an EGR functionality test or NOx test. In some cases these is also a noticeable noise like a spark knock or connecting rod bearing noise during the time of EGR valve activation.
