Hi, Does the car have a problem changing gears? Does the RMP fluctuate rapidly? By the way, I have the same car. I encounter almost the same problem as you. The mechanic put the car under diagnostic and that I needed to change three sensors. Of course I did not agree to that because logically it did not make sense that all three sensor failed. I took the car to another shop, they said the same thing. I am very stubborn so I did not have them change the sensors. I know the problem could be from lack of oxygen or fuel. I decide to clean the MAP sensor. As soon as I clean the sensor, the car start to run like it was a brand new car. The HP increased, the pick up increased. All because the dust built-up blocked the sensor from given an acurate reading. Let me know if your RMP is fluctuate rapidly. Thanks, Mike
