""Lexus dealership had difficulty determining what was causing the knocking noises coming from the engine. At first they thought it was from the spark plug coils and replaced them,but it did not fix the problem. Then said it was from the fuel injector and replaced that. Car does not have knocking noise to the extent it was before bringing it to the dealership for repair. However, I still hear a random noise on start up similar to the noises heard before and wonder if this totally fixed the problem.""
