After fixing the injector switches, EC2, PCM and triple checking all the ignition and injector circuits I STILL have an engine that runs like sh.t. 2300 rpm full throttle. I'm beginning to suspect an internal problem like an apex seal or O rings. Tomorrow I'm having a professional mazda compression test done.  
 
Is it running incredibly rough?  It's semi-likely that you could have a stuck apex seal as long as the engine has sat around.  I think Ed is our resident expert on trying to free those.  Even an unprofessional compression test would tell the tale.

Your neighbors must get tired of that black cloud over your house all the time.  I'm starting to think you and Al need to take a trip to New Orleans and have a consult with one of the voodoo folks :-)
 
Seriously, I'm sorry to hear of your continued problems.  I can only imagine how frustrating it must be.  Hang in there.
 
Rusty (feeling better about my engine with every message I read)
