Having a local shop take a look at the motor. They told me the motor is:

1) running rich, they dont know why
2) ecu is spitting out a Map Sensor error

They are suggesting I just get the wiring redone, where it is just a simple plug and play. Or I find someone with a working map sensor, and see if its just my map sensor that needs to be replaced.

First of all, wiring is a complete mess. Whoever did the wiring did not solder or even use butt connectors, just electrical taped 2 wires together.

If it's just the map sensor that needs to be replaced, that would be the cheapest option but I would probably run into more problems in the future just because the wiring is horrible.

Question is: What should I do?

(killing myself is not an option)

if your profile is correct, and you have a 2nd gen 3sgte, the map sensor itself will not create a rich condition, it controls the factory boost gauge, is used for fuel cut, and a check for the ECU when you first turn the key. but if your map sensor is not working, IE: bad wiring or unplugged, the code it sets will put you in "safe mode" which will make the car very rich and slow because of the retarted timing.
who did the wiring? if its as bad as you say, i would definetly consiter pulling it out and having it all fixed properly. bad wiring is a fire waiting to happen.
trust me, its no fun watching all your hard work melt to a pile of goo on the side of the road.
if you have some electrical know how, you can trace each wire, and test for continuity, then fix each connection yourself, it just takes time and paitence.
otherwise,
what kind of condition are ignition components in?
o2 sensor?
like was posted above, the 2nd typicly runs rich from the factory, but not so rich that it dont run decently.
