Hi. I'm new comer.  Asking here cause Fast Furious does not active like  this sub forum.

Here is my question :

I have recently  bought a second hand Toyota Wish last month. Car mileage is 140k km as shown on the odometer. Price is good Only RM32k. Cheap because I buy it from direct owner. Car manufacture year is 2007 based the number wrote at the chassis. Solid white colour. I dunno about the engine. But no VVTi mark on the engine cover. Only shown Toyota D4. The transmission is 7 speed CVT.

Problem :

1) Car jerk at low speed.Look like the CVT. I dunno how to explain, but it is like manual clutch car behaviour. Still not yet change CVT oil. But change the oil will help?

2) Rough sound and sluggish at low speed. Not sure whether engine or CVT. But it sounds rough. Currently use Synthium 3000. Any oil good for make the engine more silent at low speed?

3) Any other thing I should change? I have change completed set of hydraulic mounting. Thinking of changing fuel filter for next services.

Hope can help. Thanks
