Car dies, wont keep an idle, code 32 and 34 stored
So, recently, my car wont stay running. I have a 1988 GTA 350 TPI.
The car starts fine, then dies. If you start it and immediately feed gas to it, the car stays running fine, but once the foot is off the accelerator, it dies again.
I drove the car to Oreilly's since it is free to use their code reader, and it threw a code 32 and 34 - low MAF reading, and EGR failure.
From what I have read, the EGR valve shouldn't be causing the car to just die, should it?
Anyways, I have read a little bit on the issue, and it seems it causes surging, but not killing the car.
I am a college student with about $100, and would like to get my car running again. I'm not as techy with the car as most members, but would love to learn, and want help diagnosing the problem, or places to look.
Any help on the issue would be great. If someone has a detailed tutorial on how to take the TPI setup off to get to the EGR Valve that would be awesome as well.

Hmmm...I was also thinking a possibility of the TPS sensor being bad.
What are the usual problems that happen when the TPS or IAC go out? Does this sound like it would be the problem to anyone else?
The car has been adult owned in california, completely stock, and has 48,000 miles on it.
