Not sure about primary or secondary resistance, but when I measured the resistance across each coil pack, I found the front ones were around 1.1-1.4 ohms, and the rear ones were 0.7-0.9 ohms. Mine would missfire at over 1.1 bar.

Measure the resistance, and if there is a huge disparity in values, you know the coils are dead at higher boost and fuel levels
