1.8T starting problem

[Gary23]

Hi Im new to this forum I am hoping that someone can help me with my Golf mk4 1.8T 2002.

The trouble is that when I have left my car for a long period of time it struggles to start sometimes it takes 5 to 10 times before it starts but sounds like its only running on a few cylinders!!! after a while it clears and drives fine. There is no EML light on aswell so now I am not sure where to check next!!

Does anyone have any ideas of what to check for next any help would be appreciated.

Thanks all.
