1999 Toyota 4Runner ProblemsAutomatic Transmission May Not Shift Correctly at High Mileages
At higher mileages, (125,000-150,000) the automatic transmission may not shift correctly. This can be caused by the throttle position sensor being out of adjustment or a shift solenoid needing to be replaced. Typically the transmission does not need to be completely overhauled.
When a mass air flow sensor problem occurs, resulting in a loss of power or hesitation on acceleration, the Check Engine Light will illuminate, perhaps indicating random cylinder misfire. The mass air flow sensor may respond to cleaning, but replacement of the sensor is best.
On higher mileage vehicles, an engine misfire may develop and/or the Check Engine Light may illuminate due to a failed ignition coil. It is not uncommon to replace all the coils when the first one fails in order to prevent return trips to the repair shop.
