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.
If the car will not start, the most likely problem is worn or corroded solenoid contacts in the starter. Usually, these parts can be replaced without purchasing a new starter.
The evaporative emission (EVAP) system may illuminate the vehicle's Check Engine Light due to intermittent failure of the charcoal canister purge control solenoid valve or canister failure. Upon failure of the charcoal canister, debris may circulate around the EVAP system causing other emission control problems.
