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.
