I have a 2003 SLE and my RPM gauge randomly goes up and down while driving down the highway. There is no power loss or gain when this happens so its obviously not an engine problem. I had the Service Engine Light come on and got a code for a bad sensor that is the crankshaft position sensor. I replaced that and its still doing it. What else could it be???
