Wrong spark plugs? What spark plugs did you use?

How did the coil packs look?

Are you sure the coil pack connectors are all the way on?

It would appear that your problem is on cylinder 4, 5 and 6. So if all those other items are ok - then your Variocam control may not be working on that side.

well i ohmd out the coil packs and i checked spark on that whole side and the plugs are beru or somthing like that, the conectors i toolk off and ohmed them out too and reconected them 2 times. the variocam is the onlything im not 100%sure about because i lack a good scanner that can show me adaptaion values. one question that is off the subject do ya know of a awsome scanner that is not horibly expensive that will tell me the values im looking for
