BMW 3 series 2.0 2002 - Misfire under load #

Hi all, need some help off a BMW man please.

Have this 3 series in with a missfire under load and it's not ignition related.

I could do with some live data values for the Vanos as I'm not sure what good values are, I think this is where the problem lies as there doesn't appear to be much vacuum, infact theres very little.

Chris.

If it is Valvetronic, they run with very low vacuum at idle.

Eccentric shaft,s wear.

Google valvetronic.
