Best Answer

Probably your mass airflow sensor. It's a small electrical component located in the tube that goes from your air filter housing to the throttle body. It sticks down into the tube and sends a message to the engine computer to tell it the proper mixture for fuel and air. Check first to make sure the wires and connector going to it are hooked up and not damaged. Good luck
