Hey Walkerboy,
Obviously the problem I had with my 8valve didn't start with hitting a puddle, but the symptoms your having are exactly the same as I had.
Car from cold 'hunts' a bit on idle and doesn't want to idle? Car 'bogging down' on acceleration and stalling easily when revs drop...smelling of fuel.
Car is obviously over fueling for some reason, any codes from VAG?
What solved mine was loose connections (three wires running into plug right next to Dizzy), the other thing was broken wire at connector next to coil (black square box just under wipers on right). My advice would be to check all wiring/connections as it appears a common problem for many to be bare/exposed or loose.
The other thing could be the Lamda probe, but this would show if you have it tested.
Keep in touch with progress, good luck,
Stewart
