Does this have a TBI on it? Or is it a multi port fuel injection. Try snugging up the intake manifold bolts to start with, and run some fuel injection cleaner threw the gas.

It has TBI and I get where you are going. I will look for vacuum leaks.

Also since it is a TBI watch the 2 injectors spray. The fuel spray should be a nice cone shape with no droplets at all. Thats where the fuel injector cleaner comes in.
