Low EGT and 14.7 equals lean by lack of fuel. Extra air and lean would get hot. Fix the TPS issue, and then go from there. The TPS tells the ECU your intention. If the voltage drops to almost nothing in that spot, you will go into fuel cut.
This is all assuming you do not have DTC 34 and are...
51 is the idle switch, 41 is the TPS position. It matters.
For the O.P, nobody has seen your car but you, you have to find out yourself. How much fuel pressure do you have? How good does the spark look in air? Bright white with a blue tint, or kind of yellow? The coil pack would not be my...
Ownership. Broad stroke for many issues, which don't necessarily mean you.
I have had many, and the car is as reliable as anything I have owned. As for reviews, I uploaded others for your enjoyment. :)...

HKS Turbo Exhaust. Do not get the "Sport Exhaust" that is for naturaly aspirated cars and has a baffled muffler. This is quiet and looks stock. Power gain was noticable with out a boost controller to help on a stock...
20 seconds is not going to burn your starter. You must let it cool at that point. As you have notice, that is a symptom of a problem.
Hook up a fuel pressure guage. Get pressure so it runs. Then watch how fast it drops. You could have an injector bleeding down.
Holding the pedal to the floor goes into clear flood mode. You didn't do it long enough.
Work on your wording. I was going to ask just how it kills the injectors, because it does no such thing. Unplugging it takes power from them. Then I realized that is what you are trying to say.
So...
Next time save yourself a few moments and just put your pedal to the floor. Do not pump the pedal.
DTC?
Why? You think the impedance is wrong? You simply unplugged it or bypassed it?
How does a MAP sesnor clean up the engine bay. I myself use a degreaser and rags.
Hitachi makes a reliable and accurate MAF sensor. There are many aftermarket upgrades that are not plug and play.
To use the term loosely, fuel trim is adusting to the car and its driver. Both short and long term. The oxygen feedback as you have correctly stated is for the cat. 14.7:1 is not where the car runs best, it is where the cat runs best. You are right on track. Short term from the oxygen helps...
