Q&A

Changed coil pack, plugs, ignition module and problem remains.
Removed coil pack and removed plugs...they each look the same, the "boots" and inner springs look clean as well as the plugs...the plugs each look the same...looked at the pins on the electrical connector to the ICM and there is no oxidation. It appears the ECM is not getting the confirmation signal that #2 cylinder is firing...What else do I consider except the ECM.
