My car is 2005 myvi 1.0SR.Someone please help me..my car been jerking a lot lately.

It happens mostly after engaging first or second gear.. it would be like hiccups. The RPM would fall suddenly and go back up again.. this happens when i am pushing on acceleration pedal also.. Sometimes my car dies off at junctions.

Its especially dangerous when there is a junction on top of a hill. I am afraid that the car would die off and go backwards. So far i done somethings to solve this problem to no avail:

1. Change to Iridium sparkplugs
2. Clean the throttle body
3. Change engine oil & air filter
4. Put in fuel injector cleaner

Any ideas on what is wrong? When i bring the car to SC to clean throttle bdy they say i should change the plugs. After changing the plugs, the problem is still there. Could it be the plug cable? OR the fuel filter? Or the alternator? O2 sensor? I dont know where to start..

Thank you in advance.

I need to ask sifu..

Myvi 1.0 ejVe engine using timing belt.. mine clocked 80,000 km edi..

so what's need to change? other than the timing belt of course..

I heard need to replace aircond belt thingy.. ?? Need service aircon?

I got this problem before at rear side.. its bearing, very noisy "wuuwuuu " sound la.. cant remeber how much they charge me, but its expensive.. rm150 should be reasonable.
