Okay, just replaced my Dizzy with a FieroStore rebuilt unit, and now get a Code 42 on startup as well as poor running. Shutting the car off and re-starting it solves the issue. Re-starting the car always solves the problem.
Would this likely be an issue with the ignition module itself? The module that came with the dizzy looks to be a cheap brand unit. The car runs fine though after restart, and it does run even with the code 42.
