Code PO343 hard starting cam sensor fix LS1 LS6 Just wanted to post FYI I was having a slow starting issue with code PO343 on an 02' LS6 engine, once started everything was fine. I replaced the cam sensor & has solved the problem so far (started hot & cold about 12 times). AC Delco part is about $70.
