My engine light is on and I took it to Toyota for diagonostics. The car is running very badly. No power. The gas milage went from 27mpg to 15. Our own auto mechanic says that we must replace the knock sensor or we will not get our performance back. He says it is controlled by a computer chip that limits the amount of gas avaiable to the engine in order to protect the engine from overloading.
Please help because my husband and I are in a battle. I think the engine needs the fuel injectors cleaned and generally needs a tune up. My husband says that will make no difference until we get the kncok sensor replaced.
It will cost $1000 to replace the sensor because our Rav is 4 wheel drive.
Help us please
