Ditto, this is a more common problem then the others. I had a 97 Cadillac catera as my first car. Within 2 months of putting in a new engine i lost 3/6 cylinders. I did the same exact process as you and it turned out to be the wires.

Already did the following:
Swapped Plugs
Swapped coils

*Engine is running fine! no problems running! cant seem to figure this out... The engine light, comes on and off inconsistently once it is reset. Days, weeks... not directly after the light has been reset...
Anyone have any ideas or help!?
