Clay,
I agree, it sounds like way too rich at idle. I had similar symptoms on a friend's 380 SEC. Turned out to be the air flow metering plate was not fully returning at idle. I took the intake apart and cleaned everything up with mineral spirits, put it back together and it ran like a champ.
I've heard that you can spray carb cleaner inside the manifold while holding down the air metering plate to clean the pivot point.
Good luck,

Ray

Well Guys,
This will be the last time I write about my problem, so not to take up space. The car almost wants to start on 1st. turn of strater, but dosen't and you have to hold pedal to floor and then it starts right away. Played with fuel dist. counter clock wise leans it out, but it idles up and down between 750 and 900 but still running rich. Black smoke at idle and alittle at higher rpm 2000-3000. It's like its getting too much fuel. Runs on highway ok, but still have battery draw when tested with neg. off to a ground on car. What would make it run so rich and cause the draw ?
Only after having fuel filter changed ? I forgot you can smell the gas also, but can't see any leaks by engine or fuel pumps. I know to many questions.
Someone give me some help.
