whats wrong with my car

[mhicke]

hi i own a renault megane 03.It seems to be giving some trouble just lately.a few times it didnt start when i put the card in and press start it chugs and i have to press the excelerator a bit to get it going,now its only happened a few times.but the other problem is the gears seem stiff when changing,and if im on a slant uphill taking off in 1st it feels like im taking off in another cause the car hegs like it cant take off.
