charles Posted August 31, 2003 Report Posted August 31, 2003 2.3 petrol 97 90K miles with low rev i hear a rough pinking sound driving slowly in the first or second gear. the sound fully disappears with higher revs.firstly i thought the sound came from the gearbox, but i do not hear the sound driving away with slipping the clutch and higher rev. i read about carbone polution in the combusion chambers which could cause pre-ignition (pinking sound). some other drivers with same experience?
