Ignition Module
Alright, I'm refering to the little box locating directly above the ignition coil on the passenger side cylinder head. I believe this to be an iginition module. What does this do? Since the ECM takes care of timing and the coil fires the spark, what is there left for this module to do. Really, I'm trying to narrow down a missing cylinder and I've eliminated the opti, wires, and plugs from being the problem.

Re: Ignition Module (donhall)
So if it had a problem it would be affect everything equally, not just one cylinder. Hmm, argg. I was hoping that was it. Time for a compression test then, on a brand new engine too. err. Heck, I might replace the stupid thing anyways, everything else in the engine bay is new pretty much.

The output of the ECM does not have the ability to control the electrical current through the coil directly. The Ignition Control Module is driven from the ECM and "amplifies" the current capability so it can drive the coil. Plus, in some models, the Ignition Control Module controls the dwell time.
