When i bought the car back in Jan 2004, the guy told me its the EGR valve noise. that it will be quieter when warmed up. It doesnt go away when the engine is warm, not even quieter! I fitted a K&N induction kit and it was even more bludy louder! Please can anyone help!
Also i was told fitting the induction will actually reduce power as it isnt calibrated to the ECU? any help will be highly appritiated. thank you! :P
