Engine hesitation on startup.....bad spark plugs?
So the past couple days, I've had a slight hesitation when starting.....primarily after the car has been sitting overnight. Instead of it sparking upon turning the key, I have to hold it a couple seconds longer for it to catch....which it does.
I have NGK Platinum spark plugs in there now that I've been meaning to replace, but haven't gotten around to doing so. They have roughly around 40K miles on them =O.
Anyways my guess is a bad spark?
One other thing I'd like to mention, I bottomed out pretty bad on a speedbump over the wkend....is it possible I may have pinched a fuel line underneath the car? It sort of feels like the engine hesitates b/c its starved of fuel. Ideas?

Spark plugs...coilpack/s...high resistance in the wires between the plugs and coilpacks
Dirty throttle body
Let us know if your spark plugs are black from running rich....
How's the battery and battery connections?
could be a lot of things... you should VagCom it just in case something funky pops up.

Probably the FPR or fuel pump.
Make sure the vac lines around the FPR are good. IIRC, there is a valve in the fuel pump the prevents fuel from backflowing into the tank. Maybe that's bad? Otherwise, a failing FPR has been known to cause delayed start up times when the car has been sitting.
