Installed the M50 manifold on my 328i M

[m3f_frank de j_902cad5fe4]

Oke so I installed the M50 manifold on my 328i M.



Now here we go.



When I started the car for the first time it turned of immediatly.

Second time it runs realy bad so I think I let it run for a while.



But it stays running bad at Idle.



After a couple of mins I took the car for a spin. When Accelerating the car is doing a great job now but with a constant speed at low RPM's the car is shaking and the idle problem is still there....



I can feel the improvement of power under acceleration in every gear.



But I can't get the Idle good and the problem from cruising at low RPM'

s



Can someone help me out here???

sounds like an intake vacuum leak. check the hoses.

btw - what is a 328i M ?

Second the motion about the vacuum leak and what is a 328i M?

[m3f_frank de j_902cad5fe4]

Hehe it has full Mpackage everything.



Head is flowed too.



Btw if it is a leak it should run bad under accelerating too right but is doesn't.



When I hit the pedal it is accelerating like crazy. 0-60mph increase by almost 7th of a second and from 0-top end increased even better



So I don't think it is a vacuüm leak or anything??



Could it be the learn process??

Do say it isn't an intake leak until you check and double check....it sounds exactly like and intake leak. After that...check the idle control valve and hoses.

Yeah sumth like that.
