2000 Toyota 4Runner ProblemsHesitation or Misfire Due to Failed Mass Air Flow Sensor
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.
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.
