Default Initial fire up

Frequently on starting engine it seems to fire up on only one or two cylinders and after a few seconds comes in on all 4.
Usually it's later on in the day after its been driven in the morning and also when you car has not been used for a couple of days.

Any ideas would be appreciated. Cheers.

what grade plugs are you running, could be if your running colder plugs the they aren't being cleaned on the morning drive (if the car isn't seeing much boost) so makes it a little harder to start.

Hi thanks for the reply I'm running pf7 plugs. And yeah your right the car doesn't see much boost at all through the week as it's only a 4/5 mile trip to work. Cheers.
