1998 Q45 RPM problem

[andre1038]

Hi im just wondering what could this be? i put the key in and start my car and then the rpm goes crazy bouncing back and forth from zero to nine. of course im not moving im just idling in park not reving my car. is it some lose wire or did a switch go bad??? here is a pic of me not with the car started, it does the same thing with it started or on the ON postion. notice im at zero mph I have it in park and havent even started the car and the RPM is already at 4000. Let me know what could this be thank you. O this is a well cared for Q45 only has 85000 or so on it. It just started happening out of nowhere.[IMG][/IMG]
