Your engine vibration issue resolved after spark plug change?
try changing ur engine mountings.it will help.
Pls share where to change at $130. Gd lobang must share share.
I found it from this forum, just changed spark plug and EO not too long ago.http://www.mxtradings.com/call them before you go. I should had done the throttle body cleaning first (they can do but they don't have the computer to tune your engine) then change spark plug plus EO change. When they remove the cover, I can see thick sticky slug on the internal wall. If I have sone the throttle body cleaning then can inspect how effective is the cleaning process. If not so clean still can spay some solvent on it.If you use Vpost or travel to US then can buy from there ~USD50+ per set. Labour cost is S$30 for latio.
