| hmmm.... simply....
i was driving downhill...
gear on 2nd to prevent the car going down too fast...
i didn't have my foot on the gas...
the rpm was first steady at around 1600...
but then it rose up to 2000 itself and the car speeded up a bit...
after two seconds... it went back to 1600 again and the car slowed down...
from the beginning to the end... i didn't gas the car...
why did the rmp rise up to make the car speed up when i didn't gas it?? |
