New with sick 2002 986

[neumaiek]

Hello from North Idaho!
My 2002 Boxster S (90k miles) suddenly lost power and throws random misfire codes P030(0-6). Replaced all coils and no real change. It is now creating a huge cloud of white stinky smoke very robust! Clean MAF and ran it with the MAF disconnected. Same. Engine sounds horrible! My next guess is the AOS (cheap parts).

Any ideas or suggestions would be great! Very frustrated as this was my first Porsche and I really like it. Wife has C4S - its hers.

Thank you!!!
