Hi Grandis Lover,

I have own a grandis for 3 years plus and mileage now is 115000km. It
started to give problems like lack of acceleration when air con is on. The
whole car vibrate when AC on and gear engage to drive. The LCD TV and
those on dashboard started given noisy rattling sound.

Send it to cycle and carriage and they hook up the computer but found
nothing wrong. Have since change the timing belt and still no improvement.

Can it be due to the spark plug or Engine mounting? Anyone out there have
this same experience?

Please advice.

Dragonzag...
i think the vibration from engine mounting or engine tunning. ask the
mechanic to tune your rpm correctly. the normal rpm around 1000 to 1200.
