at D while holding brake and it vibrates - you car Throttle body got problem. first step is to clean the throttle body. service about Rm 120.
if still fail then have to change throttle body.

second possible issue is engine mounting. but engine mounting is obvious. even at idle the engine vibration is visible.
cause the engine is no longer in a firm holding position.

for spark plugs, this morning I just identify my Honda city 2006, coil broke. how it broke I don't know.
while idle to drive once a while the car jerk. Honda original coil plug cost RM 500++ . better buy the spare parts yourself outside at RM 150.
