3sgte help, running rich, map sensor error Options

[markie]

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?
