According to the manual, the resistance on our coilpacks when testing between terminals IB and G (as stamped on the coilpack) is supposed to be "infinite." This makes no sense to me as I have 18 coilpacks in my possession and none of them read "infinite" across those terminals.

With my multi-meter set on the 20K resistence setting, they read 1.35-1.68 (which I think means 1350 ohms to 1680 ohms).

Anyways, my issue is this, I want to know what kind of resistance you guys see across those terminals when you do the same test. If anyone has a brand friggin new coilpack, that would be great, as there seems to be a large disparity between the ones I have. I believe the higher the resistance the better, because when I tested the "bad" coilpacks I took out of my beater a year ago, they are all on the low side (1.3s and 1.4s) whereas the "good" coilpacks that are currently in my beater and in my turbo car are 1.5s and 1.6s.

Also be aware if you test these that the temperature DOES MAKE A DIFFERENCE. If you test hot coilpacks after you've just driven your car, they are going to show a way higher resistance than ones that have cooled down.

My testing temp for all 18 that I just tested was about 85-90 degrees (ambient out in the garage). If anyone could test theirs for me I would greatly appreciate it, and if you can get them as close to 85 Farenheit or so, that would be great. If you happen to have a brand new coilpack and can test that at 85 degrees, I will be forever in your debt.

 

Just tested my old coil, 16Xk miles on it.. I got 1.56-1.57 between IB and G.

Temp was about 85-90 also.

 

Thank you for that.
