If anyone has a 3g Hemi swaped into vintage iron, have you had any problems with it idiling. steady rpm above idle, or any problems, hiccups, anomalies. I ask because mine seems to be starving for fuel. I mean, you hear a steady sound from the fuel pump and then it slows down then picks up again. You can watch the exhuast and see the vapor go alomg with the sound and the engine. I'm curious if this is just the computer learning or some other "problem".
