How to test my COP.. Does anyone have any spares?
Ok so From my other thread, I found out that one of my COPs is bad. When the car is cold, it runs on two or three cylinders, not all four. When I take a hairdryer and warm up the coils, it runs perfect. I did this test twice, so im pretty darn sure one or two of the coils are not working when they are cold.
How do I test a coil? Something about checking resistance, but I forget what to test (they are toyota coils).
Also, does anyone have any spares I can buy? That would be awesome lol.

They're hard to test because they will test fine when they work, and test open usually when they are not working. You would be measuring the primary coil's resistance. IE-put the meter to ohms and the leads where +12V and Ground hook up.
FWIW, I have a set of toyota COPs for sale posted if you are running toyota COPs.

Yes and no. I finally got rid of "the miss" I've had forever by zip-tie-ing the factory sparkplug wires to the EDIS coil pack instead of using my custom low-ohm MSD wires. So for now, I'm happy. And if I ever do a COP conversion, I want to use some mazda millenia COPs instead. I believe they're much better than the toyota COPs. Plus they're mazda parts.
