I would start with cleaning the throttle body/idle speed motor. How did you check for a vacuum leak?

Any fault codes?

i already cleand throtle and the iac valve and i used a smoke machine to check for vacume leaks. thire are some code first i had p1128,p1130,p1126 and thats when i found a hose broken at the aos, after i fixed that the vehicle ran horible until it got warm then i rescanned it and found (p1316,p1317,p1318,p1319, p015) all pending i ran the car some more and found p0300,p0304, p0305, p0306 all current

Hmm...

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

Provided you have a laptop to run these on...

- the Durametric software at $247 is Porsche specific and can do many other things like reset airbag lights.

- as a really good all-around OBD II tool Car Code OBD II for about $122
