I just got the gallery gasket job done on my 09 g37xS. The oil pressure reads fine but the car still goes into limp mode a little while after driving it and throws p0524 and p0021 timing over advanced in bank 2. Any ideas what this could be? The gaskets are fine because it’s passing the oil pressure test and I believe the timing is on the right speck too. Even when the car doesn’t throw cel lights, when I push the car to around 4-5k Rpms, it’s starts bucking like crazy. Any help appreciated.
