3. 2l v6 engine dropped a valve and blew the engine. Is a known issue on that year model. While driving the car started making a clicking noise and stopped pulling in the middle of the road with no warning. Engine light came on. Car felt like it would not pull. Once got to the side of the road, the car would not turn over again. Took it to mechanic and said it dropped a valve. Was only able to find a piece of the valve left without going completely into the motor. Now selling the car for scrap.
