Valvetronic Problem

[Ade]

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?

hi there..

for problem no 1, it might be ur manifold

Check the manifold leaking or the gasket, this is why it sound so or you can check if the engive vibrate if it does then look into the which cylinder is not working or might be one of the plug is working so only 3 is working and hence you lose power and the engine sound very loud when you rev and the engine vibrate heavily.

Can ask your mechanic to check engine mountings to make sure its not broken cracked.

Check if the exhause got any leaks or crack.

what kind of service interval u maintaining right now? do u stretch the whole 25000km?
my mum's car had the same prob..was told to reduce the service interval ti 15000km.so far so good..
just a guess...

Service? I maintain at 10K km. What problems will surface if the control arm is due?

Chester, u were refering to problem 1?
