When i start my sportage it runs perfect, but has a very lean smell coming from the exhaust and a little hickup in the idling then when i drive of first gear it runs smooth through the revs then to second and the power is gone and the car is running on 3 cylinders until the heat guage pases the first stripe meaning normal engine temp. Then it runs normal the vehicle has power and every thing is fine. Sometimes the engine check light wil come on, but mostly its off. I got to the point where when i start it cold i leave it to idle for 10 minutes then drive and no problem. i serviced it and had it checked and the only errors where the knock sensor malfunction and vent solinoid faulty had them replaced but problem persists
