Mk4 golf 2.0 GTI struggles to start..
 

Probably only once a week, my mk4 2.0GTI fail to start, it takes about 5 attemps to fire, and once running idles at 2000rpm for about a minute. Any ideas??

Could be a few things. When you try to start it does the starter turn or just tick? If the starter is fine then I would say it's the throttle control module which requires replacing the whole throttle body.
