Testing COPs

[no1sirbutler]

My ignition is acting up and I was wondering is there any way to test the COPs? I would rather know they are bad instead of just buying a new set and hoping for the best.


Thanks

you can unplug one at a time to test them.
or scan it and see which cylinder it is

Cant really scan it b/c its not throwing a code. Its just breaking up under load and my tuner is leaning towards the COPs, and thats fine if that is the problem. I was just hoping there was a test I could perform on each COP and see if it was just a couple or all of them.
