I have the 2002 limited montero model I just bought , I have check engine light now after driving it home. codes are for all 4 o2 sensors,Idle control motor, and they told me I need o replace the whole throttle body assembly. I took It to brakes plus here in frisco tx. they had the cheapest labor. They gave me a total of $2200 to fix the real problem which is the throttle body assembly and Idle control motor. I need some input as where I can get this done cheaper or where I may be able to buy new parts myself and do it or any less expensive direction would help thanks.
