Generally it's in the PCM wiring to the throttle body, I've personally never seen the harness between the pedal and TAC be bad, but there's always a chance. Also it's usually the '03 and up, yu don't see alot of the 2000-2002 like you have, but still could be a problem. You'll need to ohm the wires from the TAC plug to the PCM plug while moving the wires around to see if the continuity goes away. To be sure this isn't an incompatibility problem, you do have the TAC that came with your engine, right?
