Thread: 2005 rpm going up and down

jamal313,

It is difficult to say. A few suggestions are an issue with the valve box in the transmission; another could be the mass airflow sensor. These are just suggestions, it is not a diagnosis. It would be best to take the vehicle in to be inspected by a certified technician.

Please keep us posted.

If you have additional questions, please feel free to contact me.
