The Toyota 4Runner has a 4.0 liter V-6 engine with a four wheel drive and goes from 0 to 60 miles per hour in 7.5 seconds. It has a capacity of pulling a load of 5000 pounds but only a meager rating of 19 mpg.
The airflow of the Toyota 4Runner can sometimes fail at higher mileages, upwards of 125000 miles. Mass air flow may cause the vehicle to become idle and even stall.
Another common problem is that the 4Runner may exhibit the check engine light because of failed coolant temperature sensors. The sensor may stop working when the vehicle is fully warmed up and this can result in the check engine light going on.
A mass airflow sensor problem may occur as well which can lead to loss of power or hesitation on acceleration. This will also cause the check engine light to come on.
All of these problems can be fixed if you consult the owner’s manual.
