Does anyone know how to get this fixed without taking it to the "Stealer"ship and pay a kidney to get it fixed...?

Changed plugs and coils already... did find that Valve Cover gasket on Cyl 3 failed and is leaking... previous plug was wet at the threads....

Im posting this here in case anyone knows a good US spec BMW friendly Dealership or Mechanic Shop that can help... thanks!!!!

Car has 140K Kilometers...

Ok... this is what i did to fix it... i reinstalled the old factory coils and everything went to normal again. also cleaned the intake valve with walnut blasting courtesy of Alpina_B3_Lux and his mechanic friend... the car idles like new..!

i did replace the HPFP by his recommendation and the car accelerates more linearly than before which was more spiky. Then again it could have been the cleaning.
