Trying to finish up the baselining on the cruiser and thought I was just about done, but now I have a PO306 code. Truck is running rough at idle, but seems to be fine at rpm above 2k. It doesn't stall, but seems close. Also seems worse when the truck is started cold vs warm restarts. This started just before all this rain, so it was dry when it began and I haven't been out puddle hopping.
I have plugs, wires, cap and rotor to go on, but threads seem to indicate this not being the issue. However the same threads seem to indicate the reverse symptoms of what I'm seeing (less power on highway and fine at idle).
I ran the gas pretty low, like solid fuel light low, just before this started. Possible dirty fuel sock or filter? I will get to the tune up stuff tomorrow hopefully, but I'm not really confident it will solve this issue. Open to thoughts on what to look at next.
