How do I pass the instant objects quiz?

racecar.py 
class RaceCar:

    def __init__(self, color, fuel_remaining, **kwargs):
        self.color = color
        self.fuel_remaining = fuel_remaining
        self.lap = 0
        for k,v in kwargs.items():
            setattr(self, k, v)

     def run_lap(self, length):
        self.fuel_remaining = self.length  * 0.125
        self.lap += 1

Looks like you're setting self.fuel_remaining instead of decrementing it

self.fuel_remaining = self.fuel_remaining - (length * 0.125) did not work.

self.fuel_remaining = self.fuel_remaining - (length * 0.125) did not work.

That part looks correct. The reason it may still be failing is because it's looking for a laps prop on self, but you have lap
