I recently purchased a 2010 G37s with 92k on it. It had the Engine light, VDC, and traction control light on. After getting the diagnostic report, the car was showing a P0340 code (camshaft sensor). So i changed both bank 1 and 2 camshaft sensors. Since changing the sensors, the car will now not start unless I unplug the block 1 camshaft sensor, and will be on limp mode where it does not go over 3500 RPM. I was wondering if anyone had any idea what the problem could be or has had similar issues? if so, can you point me at the right direction as to why the car is still in limp mode, why it is still showing a problem with the camshaft and what I have to do to get it fixed?

Thank You
