A dirty throttle body may cause a lower than normal idle and possible stalling condition. Performing a throttle body service will commonly correct this concern.

Tune-up had been done at the time the car started running ruff in every gear. After the tune-up was done the problem still remained within every gear. Took it to a repair shop and they did a fuel system cleaning (Throttle body clean, cleaner ran thur engine, and stuff add to the gas) this helped the car a lot( this costed $99.95 at my local shop). The car still has a slight ruff running idle to it at 600-800 rpm, but it is getting better and helped it a lot. The throttle body might need to be cleaned again later down the road after afew weeks. Hope this helps you guys with your car, thanks
