May be time to throw a timing light on it to be sure nothing has happened. The distributor may have moved or the gear on the end may have moved from a pin sheared or timing chain. Timing light should fine these problems if any. A compression test would not hurt either. Would not hurt to check at this point. Does not sound like a fuel problem if you have a good healthy flow of fuel coming from the injectors. You should have a good cone shaped fuel pattern. Not a lazy drip look. I am begining to think your module was not the problem to begin with. All the module I have ever seen go bad is either they worked or they did not. Just a coincidence it happen to start back when you changed the module .

Just a thought. Good luck

Let us know if you figure it out.
