This article helped me to understand the concept of VVTi: http://www.drivenracingoil.com/news/...-on-motor-oil/
Quote:
This problem would probably go completely unnoticed in a car with manual transmission because a driver would compensate the problem releasing the clutch at slightly higher revs. Summary: - my problem was related to VVTi - adding more oil to 100% on the dipstick cured it - replacing O2 sensors with new ones made the engine work considerably better (more power) and made the VVTi symptoms less annoying - replacing MAF Sensor didn't make a noticeable difference in the way the car works |
