You need to check volts on the TPS sensor with the car off but the key turned to know what volts your MAF is putting to the computer from idle to full throttle. I learned this when I owned a 87 Grand National. Same theory applies here. A shop can do this and you'll want them to check the MAF, it could also be the problem. Do you know how to check engine trip codes on your car? Get a book for these as it will help you troubleshoot better. Also when the car starts too die at idle what happens if you feather the pedal to keep it running? Will it stay running smoothly, or does it sound like it's popping and misfiring? If you pedal it and it runs fine it's your TPS setting. If it pops and blows smoke and seems to misfire, your flooding it because your MAF is bad. Probably got banged up a bit and broke it. For what it's worth, your oxygen sensor does not come into play until the car has run for a few minutes and the motor has gone into a closed loop run mode where it starts to take input from the O2 sensor. All in all it sounds like the TPS to me.
