Had been experiencing vibration in the dashboard when I pedal gas hitting above 90km/h. Sent car to workshop this morning and since boss not in yet. Opened the bonnet and looked inside. Found a piece of rag inside engine bay, hmmmm ? Took it out and closed bonnet. Boss came in, took him out for a spin to let him figure what's wrong and guess what? The strong vibration no longer exist when I speed up to 90-100km/h. Workshop boss looked at me and said "Nothing wrong leh!" Wah piang!!
