WHY IS MY ENGINE VIBRATING AT STOP LIGHT WHEN IN DRIVE?

2002 Kia Spectra • 68,000 miles

Can feel vibration in cabin and steering wheel only when in drive(under load)and foot on brake. Idle is otherwise smooth in park and neutral. Changed all motor mounts but problem persists. Changes spark plugs, wires, timong belt, water pump. Please reply with possible causes. Thanks

Maybe it's exhaust related? If you watch touch engine in neutral, does it feel/look smooth? Then put in gear and watch/feel, any change?

Yes, as I noted initially the engine vibrates when in gear at idle, no vibration/smooth in neutral at idle. Why do you think it may be exhaust related? Thanks
