i have a major prob, ok my car idles fine but with i put in gear to drive it stumbles and i have to put the accelerator to tha floor for it to move i really dont know who to take it to besides tha dealer to get a complete diagnosis,and i really dont want to do that so if anyone have had this prob please enlighten me on tha subject only thing i could think it could be is the exhaust or timing.

 

has the car had a tune up recently?
Sound more like injectors than anything else to me.
But of course you also have the NG VG injectors
