Ever since I had the swirl valve replaced I have had nothing but problems again and the dealership says they can not find any thing else wrong. right now the shifting is horrible,I feel like there is no power and whenever the vehicle feels like all kinds of lights come on.Also the diesel smell is so bad that I can not drive this vehicle without windows open. The swirl valve cost me a lot of money and I can not afford to spend any more money on fixing this Jeep and then I am always without a vehicle. I have given up with the dealership and do not know where to go. The consumer is always the one that has to suffer.
