I have a 99 ck1500 vortec 350 w/68000 miles. The problem shows up when the truck is at an idle it codes in p306 or cyl. 6 misfire. Im at witts end and out of ideas. I have changed plugs, plug wires, cap, rotor bug, #6 injector twice, checked wireing over several times. Could a sluggish valve be the cause or should I just let the cel come on and live with it. :( [Quote] It was like that when I got here :twisted:
have the same problem?
