Playing with a keyboard

Hello all, I'm not much of a poster but i'll try to express my problem the best i can, thanks in advance for the help you can offer.

So i've recently started playing this game but i don't have a remote controller for pc so i've been playing with keyboard and mouse, my problem is that the W key is used to acelerate and to incline the car forward when you jump so i can't control my jumps really well when i try to accelerate and jump.... I don't know if i'm expressing the problem very well but if you understood it, did you run through the same problem? Were you able to fix it?
