nah, that's the carbon canister frequency valve working properly.

you're gonna hate it.  as far as splicing, do it out of the car.  remove
old sensor.  unplug it.  bring inside.  splice new sensor on, making the
wires maybe slightly longer when you are done.  return to car, install
and plug it back in.
