A toyota certified machanic has informed me I need to replace my mass air flow sensor on my 99 4runner. My question is: is this something that can be done fairly easily? Easily enough to have my father who is mechanicly inclined fix it in the driveway and save me some money? If so, where is the best place to find the instructions to make sure we get to it and get it done correctly?

The Mass Airflow Sensor is fairly easy to replace. It only requires a few tools: screwdriver(maybe) pliers(to undo a clamp). The sensor is located on the intake of the car. All you must do is remove the old sensor off of the intake and replace it with the new one. Make sure you do not leave any room for vacuum leaks. Otherwise, this should only take about a half hour. GOOD LUCK!!
