Hi there I have a 2006 Jetta 2.5 liter. I first had a cam position sensor code and I changed it and the code went away. Then I got a throttle body code and changed that and all is well. I then drove it for a couple hours and now I have misfire on 4 and 5 cylinder and also random misfire which I used vagcom and it was cylinder 2 that was the random one. It is also hard to start when cold. Any ideas would be greatly appreciated! Thanks.
