Looks like the previous owner removed the EGR valve. Guessing when he put in the Rochester with the electric choke. I was replacing PCV, etc when I noticed it wasn’t there. Unless I can’t find it. It’s a ‘78 with the 231. It’s been running without one. Does hesitate a little when starting out at a stop. If I push down too hard on the accelerator from stop, it stalls. Any thoughts? And would it be on the driver side intake manifold? Thanks
