Upon looking into this problem myself as I was prodded to change out my coil to plug connectors, I took some measurements. I found that two of the connectors were measuring 2k ohms and I found one that measured 2.7k ohms. I then measured the new connectors that I bought and the all measured right at 2k or 1.9k ohms. The car runs much better with a noticeable difference with the new connectors.

Pretty much what all the crap means is that even 700 ohms can make a huge difference, I know that it did with mine.

PS I have resistorless plugs on the way and will report on my findings there in resistor measurement as compared to the bosch plats i am running right now.
