Customer Question
It is a 200...

It is a 200 model Buick Century, car idles rough when stopped for a light.

Mechanic's Assistant: Is the rough idle intermittent or consistent?

Sometimes goes away after car is driven and engine is heated up. I've cleared the error code with a Cobra OBD Scan tool and the service engine light goes away, but comes back on within a day

Mechanic's Assistant: What year is your Century?

2000

Mechanic's Assistant: Are you fixing your Century yourself? What have you tried so far?

I'd like to to save monet, looks like it may be a modular part that needs replacing but not certain

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

That should cover it...the book that comes with the Cobra says: EVAP Emission Control Sys Vent Circuit Malf that should also help
