Hello everyone,

I just purchased a 1998 Mazda Millenia but after a few days the check engine light came on. I'm new to cars but I'm willing to learn as much as I can. I took the car by a mechanic and he said that I need a Idle Speed Sensor but the Mazda Dealer wants $698 plus tax. Do you know were I might beable to find it for cheaper. In addition do you know of any websites that would show me what it is. I still am not able to find a picture or digram of it on-line.

Thank you inadvance
