Beside of this problem>> "When accelerating everything is fine, but if sudden slow down from high speed, my car will stalling. What is the problem..."
Tonight I drove my car out to refill petrol, I found that my car like very hesitate to move, rev goes up very slow like no power at all, the rev indicator like very heavy, like to stick below 1000rpm.... And I hear the shift gear sound(bov sound) not similar as normal. Normally the sound is from driver side, but now its from passenger side.... Besides that, every morning when I warm up the car, I can hear the sound from rear, mostly from fuel tank, the sound is not same like the usual fuel pump operating sound(when turn on without engine start) but like "duok duok duok duok~"
This week I'll get my clutch line and will go to solve this problem as well, but before that I hope to know what is the possible of causing this happen? I hope can narrow down the faulty area.... Anyone feel free can you give your opinion? Thank you so much for your reply~
My suspect:
- AAC valve dirty
- Vacuum hose leak
- BOV died
