I just changed my valve cover and top timing cover gaskets on my 2004 745i. I started the car up and it ran very smooth so I took it for a test drive around the corner and it started to run very rough and the engine fault light came on. I put everything back exactly how it came off.I bought the Peake code reader and it gave me these errors.
273d=catalytic converter conversion (bank 2)
27bb=camshaft control outlet -vanos0
27bc=camshaft control outlet-vanos bank2
274e=misfire detection, checksum failure
2731=camshaft control inlet
2732=nw-intaken control bank2
2744=misfire detection cyl 4
2742=misfire dtection cyl 1
2749=misfre detection cyl 2
2747=misfire detection cyl 3
I worked on the drivers side of the engine so not really sure why the misfires are happening on the passenger side. Any idea what could be causing these problems?
