[QUOTE="Ade, post: 1933, member: 95"] Hi all,Been having these problems lately..what could be wrong.1. Loud exhaust - The car seems to be very very loud during revs compared to other valvies....no punctured exhaust noted...SC told me something is not right with the cataylic converter. I suspect the silencer...sifu ???2. Idling is erratic intermittently - Not sure but some say the idle control valve needs cleaning. The needle just jumps between 600 to 800 rpm intermittently.3. Vibration felt through steering when revving from 4000 rpm. I can feel the vibration of the engine on my steering. Could it be the control arm bushing is time to change? :( :( :( [/QUOTE]
