Problem is truck is miss firieing on #3 cylinder, replaced coil plugs and wires and check compression and its good. After replacing coil plugs and wires still shows weak spark on #1, 2, 3 on the coil pack. Also haveing same troulble on a ford exploder.
Why would it show weak spark on one side of coil pack?

Is it actually misfiring? When you say weak spark, what do you mean? Does the misfire go away when driving?

Yes its actually misfiring, even when driving it is running rough. Took a ignition firing tester that test spark through the wire. And it shows weak spark on the 123 and strong spark on 456.

Thanks
