take a look at the EGR valve it could be either vacum controlled or electronic either way what seems to be the problem is that the valve is stuck in the open position until the engine warms up you can gently tap the egr valve with a small hammer or a screw driver and you can see that it runs smooth, now if the egr valve is vacum controlled replace the valve. if it is electronoc controlled replace the valve and the module for the egr valve.

The code description is a giveaway.
It could be one of the coils on the coil pack. Most coils nowadays do two cylinders each. This way car makers can get away with one coil for two cylinders.(lowers costs) One spark fires the air fuel mix in one of the cylinders and the other will fire the cylinder on the exhaust stroke. If the coils are removable, and you are fairly handy with cars,switch two around, the problem will follow the bad coil.

Running on a stand is not the same as running under power...In the water, you are essentially running on a dynomometer (dyno is a big water brake) If you can prove that the module isn't putting in enough advance, it would be doing the same thing that I mentioned with the damper, only for a different reason. So...you're likely on the right track. (rather have a points setup out on the water...anything goes wrong, you fix it without a tow!!!!)

you need to have the engine coolant switch
checked,since the computer relies solely on sensors,the ect tells the computer how cold or hot it is so the
computer will make it a rich or lean mixture to start the engine,if it tells the
computer that it is 75 degrees the computer will lean the mixture like starting
a car in the winter without a choke.

coil packs? or dist engine? check coil packs for cracks and leakage on distributor egines check for side to side play in the dist shaft if any play then change it!
