Damn, I was hoping there wasn't going to be any "unseen" problems from the electrical current.
I'd just replace the wiring for the EGT gauge. You may want to swap out the gauge with another from a friend to see if it's the gauge, too.
As far as the high idle, test the normal things such as TPS and ISC motor. Heck, you may even want to go ahead and check all the sensors while your at it, just to be sure nothing else will creep up. I'm not sure how an ECU is tested, but you may want to do that as well.

There you go!
I can't wait to get DSMLink for our 1G. I want to run a MAP sensor as well on that car. In fact, the 550s and GM MAF/Translator are going to be swapped to the Spyder after that Big 16G goes on. Jenni is gettin' giddy!

Just remembered that I had a problem with my old 95 TSi and a stuck high idle. Mitsu never figured it out and a new ISC didn't fix it. Eventually I found that the throttle cable had a very small burr in it that didn't allow the throttle plate to close all the way. This only happened on hot/humid days in Iowa. I only figured it out because it eventually one day decided to stick permanantely while I was driving about 70mph on the highway and would not slow down, threw it in neutral and it redlined! New throttle cable = problem solved. I don't think that is your problem cause I can't see an electrical current screwing with that cable, but it may be worth checking into.

The throttle cable runs right next to the battery though. It is definitely burnt but I don't think damaged. I have a new throttle cable, tps, ics, and cruise control cable going on this weekend, along with DSMlink, removal of my SAFC and removal of an AEM ignition box, which all the wires go singed on.

Actually on one of my old 1G's I had the battery ground itself to the hood when I parked it one night, I came out the next morning to go to work and the battery was dead. Popped the hood and there was a spot on the hood from it arcing against it.
Put in another battery and put a piece of rubber on the terminal so it wouldnt hit the hood again and assumed I was good.
Start the car, its idling a little high, oh well, put in gear and go to leave but the Throttle wouldnt move.
I stepped on the pedal fairly hard and it went in but wouldnt release. The current had heated up the plastic inside the cable and fused it together.
Not sure if youve pressed your gas pedal or not but it may be what happened

Well, it was a fun weekend out in the sun here. Found out I toasted my CAS, TPS, fused the wires together on the CAS, melted down to wire on several other wires.
Replaced CAS, TPS with spare parts from GSX#1, uninstalled the AEM ignition box, installed AFPR, and rerouted some of the vacuum lines.
Car is running great. Boost gauge is definitely broken, but for the most part the car is running great! Also, a little brake cleaner took off most of the smoke stains from under the hood.
