No the can go faster downhill or uphill
your transmissions gone
It loses power because going uphill is harder then going downhill therefore causing it to use more gas and then making it lose power bit by bit.
gravity!
Engine is in need of tuning.
Gravity. The car is heavy and doesnt want to move, so you must excelerate to make the car go uphill. If a car is going downhill, the is no need to excelerate because gravity is pulling the car downhill.
Time for a tune up.
What does it means when car hesitates from time to time
Gravity if going uphill. Friction.
Gravity is trying to push the car down the hill. It takes more power to overcome that push of gravity. Unless you give the car more gas it will slow down.
If the slope is 'uphill' then the car is going faster
