They're located on the passenger side of the engine; between the motor mount and the oil filter. Easy to get to; one bolt and one electrical connector each.

Reduced ignition advance, sluggish acceleration, decrease in gas mileage and probably a CEL (don't recall the actual code). Never had the problem with my GTO but that's what happened with my niece's Jetta.
