P0343 is Cam Position Sensor Circut High Bank 1 Sensor A. I just installed my LS3 416 in my 02 Z06. I used the SDPC supplied sensor extension for the knock sensors and CPS. The car stated and ran pretty well for the first break in period. I noticed the code on the second break in period and I can't get it to go away. This morning it didn't want to start but finally did. It drove okay but at idle it is very choppy. I checked the connections and they are fine. Did I miss any thing in the tune that I was supposed to put some new data in for the relocated CPS? Any help would be great. Thanks.

Not really uncommon. the A and C terminals are likely reversed in the ext harness. Try reversing the the plug at the firewall, if you can reach it.
Betcha it pops and snorts during startup?

You sir have won the prize. I swapped the A and C terminal at the timing cover and all is well. Thanks for the response.
