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.

1999 Toyota 4Runner Problems
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 heater circuit for the oxygen sensor tends to have a higher than normal failure rate. Failure of the oxygen sensor heater circuit will illuminate the Check Engine Light. The internal oxygen sensor heater cannot be repaired, the failed sensor should be replaced to correct this concern.
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.
