1999, Carrera 4, manual, coupe, 174,000 miles. IMS and clutch replaced at 170,000 miles, Check engine light this morning. Noticed a rough idle and some initial reduced performance but once above 1500 rpms or so it runs fine. Pulled the codes when I got home, did some research and I'm really worried now. Looked for some data on the cam deviation using my Schwaben scan tool. It says Camshaft position 1 deviation 24.64 and Camshaft position 2 deviation -1.97, from what I've read these are probably not the numbers I need (or should have). Anyone that can steer me in the right direction to tackle this? I really apreciate it. Could this be as simple as replacing the camshaft position sensor? 

 

Thanks in advance, Jerry

P0341 is the code for cam position sensor #1 showing an open circuit due either to harness issues (shorts, broken wires).  P1340 if for the timing chain on the same bank being out of position.  Everything else are simple misfires.
