Car dropped 250 RPM and is now stuttering

I don't buy that all the sudden something would have changed.

But it apparently just did or there wouldn't be a problem all the sudden.
Don't take anything like that for granted, and see if what I suggested to do helps.
2 minutes out of your life to try it.

Or don't.

A fellow Mopar enthusiast came over and we took at look at the engine. He is fairly certain that I have a vacuum leak causing a leannout situation.

The engine rev healthily and the idle comes back when the butterfly is closed up. Without closing the butterfly the car will sputter and die.

I'm going to spray around the typical areas to see if I can find a leak.

Not sure if this matters but I recently switched from two breathers to a PCV. The carb was retuned for the PCV.

Or it has something in the jets and what I suggested will clear it.
Just because it's apparently running lean doesn't always mean too much air.
It can also be from not enough fuel.

Rev it up a bit and then throw it wide open while closing the choke all the way until it dies down and then let off both in time for it to recover.
Give it a little rev or two to clear out the extra fuel and smooth out.
Better, or problem gone?
