Truck has been surging or missing or starving at idle since I rebuilt it. Wanted to get some opinions on what it might be or if it’s just normal. The main reason I notice is because when I’m idling in to someplace, say the garage, or at the drive-thru, the whole vehicle surges forward intermittently. Or maybe it drops off instead of surging. Either way, it won’t idle smooth. It kind of bucks slightly if you just have it in gear and let off the brake.
At speed, there is no discernible miss or anything. Comes off idle quick and is very responsive. Just looking for some info from you all to see if you think this is normal or how I might be able to correct this.
‘71, stock rebuilt 350, rebuilt Q-Jet, stock manifold, breather, etc.
