2004 Toyota Rav4 Repair Question
Why would I be getting poor gas mileage?
Answer
The idling speed is erratic and such problems are usually caused by restriction ini the throttle body and IAC air passages. Getting both items cleaned should stabilise the idling speed and hopefully that resolves the higher fuel consumption as well.
What about the map or maf sensor, would that need to be cleaned as well? I just bought a Haynes manual for my car, but it won't arrive before I take a road trip. Are there pictures available to show the component locations? Thank you for any help.
The MAF is a delicate sensor which can easily be damaged and if you wish to clean it, there are special cleaners available specifically for this job. You must avoid excessive pressure/force to be directed at the sensor. It should not be subjected to shocks.
The throttle body is at end of air hose and the IAC is attached to it at bottom, with 2 coolant hoses.
