Default 1986 c4 codes 32 & 33 help!

Hi everyone, I have a stock 1986 c4 thats been giving me a hard time. I just bought it and on the drive home the coolant temp crept up to 250 when i pulled into my drive way. Since then I cleaned the radiator, and filter, and add some coolant and the car seems to be running a cooler. After i got it home, my brother and i took it out for a drive, and it ran fine. We then parked it, and when i tried to start it later, it wouldn't start. It would die if i let off the throttle and wouldn't idle without me pushing the gas. We let it sit for about 30 minutes, went back out, and it started and ran fine. The next day, it did the same thing but rather than letting it sit, i just revved it for a little while and then it ran fine and idled. Then it didn't happen for a few days until yesterday, when i drove it home, and it hasn't started since yesterday around 7. i tried this morning and it hasn't started. I got the codes 32, and 33. EGR and MAF. I've read that a bad egr will show the same symptoms i'm having. But I'm sure the MAF problem isn't helping either. I've read that could be the MAF, or burn off relays and or power relays. Any help would be greatly appreciated as this is my first corvette and I love the car!

Try the power relay, they are not expensive, a lot cheaper than the MAF. if not it is the MAF
