Mass Air Flow sensor...it's located in the air intake snorkle just behind the air filter.

Check the wiring and connections to it and try cleaning the little tiny wires with brake kleen or electronic cleaner. Be very careful as the wires are fragile.

Ther might be a little wiring diagram in the engine room to help you locate it.

Good luck and keep us posted.
