2004 Kia Optima

Does it feel like the engine is missing or there is a problem with the front end?

feels like its coming from the front end or transaxel. When it was cold in the mornings it is rougher
when the suspension is bouncing you can hear and feel the roughness Tonight when I drove on highway it feels and sounds rough Around town its rough when cold but seems to be better when its driven for awhile

Is there any noise associated with it? If so, it could be a wheel bearing. Let me know.

No noise, just rough. let me also add , and I don't know if their related but there has also been a little rough idle. I've had it scoped several times and nothing could be found. Sometimes sitting at a red light with the brake on the idle got rougher. Leave the brake off and the roughness stopped. Didn"t do it all of the time but I noticed it again this morning. Problems seem to be from the front someplace. I know kia had a problem with the steering column vibrating a little. The dealership said it was the nature of the beast.

The only thing I can think of to check is the tires. Make sure they are worn evenly and there are no shifted belts. You can rotate them to see if the vibration comes from the rear.

As far as the rough idle, check for a vacuum leak. Also, when was the last tune up?
