Barometric Pressure Sensor

[remmargorp]

Two/three weeks ago I changed the air filter in my car (1991 Plymouth Laser RS Turbo).

I was careful (I thought) not to damage the MAF sensor as it came out of the air box.

A week later (car running perfect up until this week) I here two LOUD ticks (sounded like it came from the computer) and the car shuts off. I was unable to get it to start for another hour (during the process more loud ticks from the computer area and a really bad anti-freeze smell), finally got it to start and drove it to my house and it has sat since (unable to start).

I finally got it to start today and idle for a few minutes without issue, Check Engine light came on so I used my PDA + mmcd to read the codes.

Code 25 - Barometric Pressure Sensor. I checked in the book and found it under air sensor, the barometric sensor is part of the MAF sensor unit (that's what I get from the book atleast).

My question is this: (considering I have wanted to do this anyway for a while)

Would upgrading to the MAF-T and a GM MAF sensor properly replace the functionality of the barometric sensor (if the sensor is at fault, would the error clear because it is part of the new unit (GM MAF))?

Yes. I can't remember if it's the baro or the IAT that the MAF-T 'lies' about (sends a static value for), but I'm pretty sure it's the baro. But it will make your problem go away, unless it's a wiring issue and not actually a sensor issue, or an ECU problem. You could also probably just get a replacement Karmann unit to use in the meantime for relatively cheap.
