Update:

The Injectors were professionally cleaned from a local shop and they reported them being very dirty. Now the misfire is still there but appears much later. Still showing 0 on misfire counter on GT1.

Any way we decided to go ahead with the VANOS rebuild to see if that would help. The Vanos unit was pretty Dirty so Got it looking all new with a lot of cleaning and BEISAN parts. We will also do a valve adjustment at the same time just to check as I did one only a little while back. I'll post up the findings later on today....
