2000 Oldsmobile Silhouette rough idle/vibration Sign In

I own a 200 Olds Silhouette and it runs great at slow and fast speeds. But, when at a stop and idling it runs rough. I should say that it It runs loud and has a very mild vibration. Hardly any vibration. What is surprising, Is that when you go outside the car and listen to the engine with hood up or down, it sounds fine. It is only when you are in the car and it is idling that it sounds abnormal/loud. Any thoughts?

I'd guess you're feeling it more than hearing it. The engine is probably transmitting vibration through the body, possibly due to worn motor mounts or the exhaust system grounding out somewhere.

Very true... I am almost feeling it more than hearing it. Ill check the exhaust system and mounts. Thanks
