do you know for a fact that the code that is being thrown is being thrown by the maf?

the pink wire coming off the MAF harness is notorious for going bad on 97 LT1's!!
i had the same problem. replaced the MAF and the code was still there. ended up buying a a harness from advanced for maybe 30$ and replaced the harness and as far back as i could tear the stock loom back. and the code went away after that.

one more thing, after replacing the MAF did u reset the PCM?
u can do so by unplugging the battery or taking the PCM fuse out on the dash, near the driver side door. take it out for 30 secs.
