I've got an 80 Buick century with a 3.8 liter engine and 2 barrel carb. Here is the issue....
The engine runs rough when I'm stopped in drive at like a stop light for instance. It doesn't die, but sounds like its going to. I've tried everything I can think of.... New choke pull-offs, new plugs, wires, cap and rotor. I have cold stall issues when I try and start it in the morning and it runs really rough in drive when I give it gas for the first few mins until it warms up. In other words if while its warming up I give it too much gas in drive I feel it loosing power and too little gas wont get me moving. Once its warm it runs fine, but it still runs rough when stopped in drive. It seems to run rougher when stopped in drive once the engine fully warms up.
Could it be a vaccum issue? I've inspected most of the hoses and they all seem to be intact and in good condition. I should also say that it smells like its running really rich.
WHAT COULD IT BE?
