help 08 R56
 

So I had my head rebuilt,. Added new rings do to oil in number 2, and so on.. Engine is back together went to fire it and I have misfires in number 2 and 3. Changed plugs and did the coil swap and still same issue. Runs ok at high rpm but idles bad at low with the misfires. Any help please a living nightmare. Checked timing 2 times and it was dead on.. Could a Vanos gear be the issue??? already change the intake side?

e-mail me at wind715@outlook.com if any one can point to a start point.

Thanks

Robert

Start with:
MAF sensor, coolant temp sensor,
if either the intake or exhaust cam is one tooth off it will shoot codes.
vacuum lines?
You didn't mention if it does it hot or cold or both.
Sorry for the late reply,
usually lurk on the Porsche forums.
Good luck hope you get it handled.
