got a lot of the interior apart currently. some mice got in it and they ruined some wiring, and have defiled the clean smell of the car... engine runs like crap at anything over half throttle and the idle is hit or miss. i have some work to do..

thank you, woodmv! Just trying to get the car back to its old self.
Having idle issues with my car though. The engine will start and idle roughly. It seems as though its not getting enough fuel. If I depress the plunger on the TPS, the engine's idle will increase and smooth out and run normally. Sometimes if i run the engine at half throttle, it will smooth out and run to redline at half throttle. Full throttle causes the engine to stumble. I have replaced the following parts with no change in running condition:
-ecu and surrounding sensors
-tps
-afm
-cleaned the air filter, tube in front of the radiator, and ruber intake boot
-cleaned the throttle body
-replaced the exhaust with a system with gutted cats to test for restriction issues
I cleaned the wiring to the ecu and surrounding sensors and replaced all of the surrounding sensors with known good units. The injectors were cleaned and tested by witchhunter in 2009. I pulled the dynamic chamber and upper intake manifold off and inspected the wiring and the injectors an all appeared to be good condition. The engine has ran perfectly since i swapped it into the car in 2009. The car got some mice in it and this is when it started running funny. I have pulled the enterior out and cleaned all of the nests and scrapped the fabric sound deadening. i did not see any chewed wiring. I have not adjusted the other tps that I installed and will not until I figure out what's going on. The other tps would cause the idle to smooth out near instantly when the plunger was depressed. The one I installed takes a few seconds of full plunger depression before the engine decides to run well.
Here is a video of the engine starting and running:

Well, that decent weather came and my RX-7 is back up and running well. Mike (myfree7) was here to witness this epic event and we even went for a quite spirited drive! Time to replace the exhaust and go back to my stock setup. I will be posting more pics of the car. But for now:

Found the issue to be traced to a faulty leading coil. It tested good originally but showed its true colors during a flooding incident while diagnosing the rough running issue on Friday. Replaced both coils with new oem Diamond coils and the replaced and adjusted the TPS. I adjusted the idle and mixture and the engine runs better than ever. So today, I took gave the car a bath and took it for a short drive and snapped a couple pics. Here's what I wound up with:

Running excellent after fixing the rough running and adjusting the TPS, mixture, and idle:
Pulling back in after the drive:
A quick should with one of my 944's:
A short acceleration video showing no running issues :

Pic from when I got the car started for the first time this year:
Ran great and started without issue:
Engine was in serious need of a clean up:
Got the car parked in its new spot:
Car spent some time in the garage as I was cleaning it up a bit:
Had my son Max helping me buff the car:
Took a couple pics of it with my RX-8 yesterday:
