Mine does it on a damp day.

Does the same when I wash her too.

I've put mine down to having an induction kit.

Have you checked to see if your MAF is working?

 

i should of stated too, that mine is the same does it when its been damp, but i dont have a induction kit, just a uprated filter.

How would i go about checking to see if the MAF is working?

I do have a AFR gauge which seems to read correctly as if everthings ok.

 

Generally, this could be a couple of things, Dependant upon how it feels, Plugs Etc but generally with electrical hesitancy it's more severe..

Or more likely a tired O2 Sensor where the heater within it takes forever or it does not heat up electrically at all & relies on the Engine gases getting it hot, Once hot the car then drives fine & responsively.

May Moneys on the Lambda / O2 Sensor as replacing it has always cured these symptons on my Scoobs.

I have also found a far cheaper alternative for my application here, You'll neeed to check the plug type
