I recently finished replacing the upper and lower timing chains on my VR6 as well as the Valve cover gasket. After putting everything back together I took it for a test drive and had noticeable improvement in the drivability, but my check engine light is still on with the P1340 code for the Cam/crank position sensors and the engine still idles rough and sounds like it’s skipping at idle. I know the timing is correct and I already replaced the sensors for the cam and the crank. Any suggestions at all for possible fixes? I’m new to Working on VW’s so any help would be appreciated.
