Thanks for the replies guys, i did have 2 wires swapped on the passenger side bank. Runs like a top now. Mr_Rich, I am slightly worried about the cam gear itself but I did run a bore scope down and had a buddy spin the motor over and the cam gear looked fine. The distributor gears were worn paper thin on the ones that were still left. The teeth getting wore thin seems to be a fairly common vortec problem, happened on my wife’s suburban and my mother’s Yukon. Caught those before they failed, but this truck I just recently got and have no idea how long it had the po1345 code for before I got it. If it does fail quickly it’ll get a zz502 cam.
