Hi all I'm new here and wondered if anyone could help me. I have a 2008 golf gti 2.0t fsi with 62,000 on the clock, my problem is the car seems to accelerate by itself when idil, it reaches 1500 rpm then drops, some times reaches to 2000 rpm, the power still seems to be there aswell, I have checked the pcv valve by taking of the oil cap, the car started to splutter so I assume everything's fine there, just hoping anyone can help ???? Thanks
