What is the cause for this vibration which only happens occasionally and usually at around 50 km/h and 80km/h only for 1999 Toyota Camry 2L 4 Cyl?Vibration at 60 - 80km/h. More noticeable when on load like going up hill. When accelerate hard the vibration goes away. Only happen when gently accelerate and when reach speed around 60 - 80 km/h the vibration comes on.
Letting go the accelerator the vibration goes away. Vibration only occurs when fuel is applies by pressing on the accelerator. Spent over $500 for mechanic to replaced Platinum spark plugs and plug cords plus tuning done at certified Toyota service center but the vibration problem still exist. What is next? Wanting to know the exact cause to this problem. Pease advice.
