    I'm havin really low idle issues and I have no idea where the idle air control valve is. Guy at orriely said you should clean that first before I replace the MAFS

    :) Your idle air control motor is attached to the butterfly that you open and close, ie. the throttle, if you folow your plastic air inlet hose from the air filter back to the engine, at the end will be your throttle valve. On the side of your throttle valve will be the idle air control motor. You can use cleaner that is made for fuel injected throttles to clean the valve. Good Luck

    yeah I dont think there is one. i can't locate anything like that and when I looked for a replacement part I couldnt find one for the 2nd gen tacomas. The truck is running great now. Its not dropping below 400 anymore and sounds normal again!

    :eek: I am sorry that I posted some incorect info about the IAC motor on the throttle body. I should have studied the picture more before I posted and I see that Whippersnapper 02 and NMC are correct and the throttle control motor compensates like a IAC motor would.
    I guess going from a 98 GM to a 12 taco has a little bit of a learning curve attached to it. I am glad that the throttle cleaning has fixed your problem.

    IACV is a relic from the days before electronic control throttle. With the throttle cable eliminated from the new engines, the ECU simply uses the same butterfly valve for idle and off idle operation.

    Dude at Oreily probably drives a J#$P. :eek:
