Hi bros, I got a problem & I hope someone with good mechanical knowledge can help me out. Mine is 1 year old 1.6SX.
My car has a vibration problem. Sometimes when I press on the accelerator, there seems to be vibration at the engine side in front of the driver. The engine is rough & pulsating like you are driving on flat tyre.
The frustrating thing is that it does not always happens. Sometimes on a journey, it happens a few times. Sometimes it does not happen at all! I have sent it to an SC twice to check but everytime I am there, it does not happen no matter how they tried. They even did an engine diagnostic but detected nothing.
Another thing is that at traffic lights in D & foot on the brake pedal, the engine vibrates loudly like it wants to take off by itself but when I shift to N, the idling becomes normal.
By process of elimination, I have:
a. change spark plugs at 20K. The set (Champion) looked carbon fouled, i.e., dry but quite brown around the tip &
b. done alignment & balancing. It is not wheels & tyres because if it is, I can feel it the whole time but now this is not the case.
I suspect:
a. gearbox or drive shaft?
b. engine firing?
c. bad fuel?
Any clues or suggestion which SC best can help me solve this problem? Thanks.
