What is the solution for Odyssey idle vibration?

[MacRuby]

Odyssey vibration causes and solutions are as follows: 1. Severe engine carbon deposits: The most common cause of car vibration is dirty throttle or excessive carbon buildup in fuel injectors. When there's too much carbon inside the engine, the gasoline sprayed by cold start injectors gets largely absorbed by carbon deposits, resulting in over-lean mixture during cold starts and making ignition difficult. The solution is to clean the fuel system and check if the idle speed motor has carbon buildup that needs cleaning. 2. Ignition system issues: Check the working condition of spark plugs, high-voltage wires and ignition coils. Poor ignition system performance or bad spark plug firing can also cause such faults. The solution is to check if spark plugs have excessive carbon buildup and replace them if necessary.
