Okay, did you clear the codes? If all of these codes came on at once I would think the PCM is bad.
P0442: Evaporative Emission Control System Leak (small).
P0300: Random/Multiple Cylinder Misfire Detected.
P0420: Catalyst System Efficiency Below Threshold (Bank 1).
P0455: Evaporative Emission Control System Leak (large).
P2108: Throttle Actuator Control Module Performance.
P0521: Engine Oil Pressure Sensor Range/Performance Problem.
P0106: Manifold Absolute Pressure (MAP) Sensor Range/Performance Problem.
P0101: Mass Airflow (MAF) Circuit Range/Performance Problem.
P0068: MAP/MAF - Throttle Position Correlation.
P1101: Intake Air Flow System Performance.
P0326: Knock Sensor 1 Circuit Range/Performance Problem (Bank 1).
P0331: Knock Sensor 2 Circuit Range/Performance Problem (Bank 2).
P0700: Transmission Control System Malfunction.
P0102: Mass Airflow (MAF) Circuit Low Input.
P0113: Intake Air Temperature Sensor 1 Circuit High Input.
Has the wiring been tampered with? Also, you may have corrosion at the PCM electrical connectors so please check for that as well. If the fuses are okay (test with ignition on) I have left the location and instructions on how to change out the PCM, you can get a preprogrammed unit by searching Google or Ebay. Check out the images (below). Please upload pictures or videos in your response of any problems so we can see what to help you with.
