Love to offer some help Aaron, but I'm a carburetor guy. Have no clue about computer controled EFI motors.
This board is for B-bodies (your car is based upon the M-body front wheel drive V-6 body) which includes the Impala, Caprice, Kingswood wagon, as well as the Biscayne, and Bel Air made from 1958 to 1999. Here we talk about beating back rust and trying to find parts that haven't been made in 40 years. Our interests are in hot rodding and restoring old American rear wheel drive, full frame, American made V-8 powered cars.
There may be a Chevrolet technician reading this board that fixes old cars for a hobby that may be able to assist with some advise, but I can not say when or if he will respond.
