Found out it was a misfire in cylinder 3. Just replaced the spark plug, and ignition coil, but nothing has seemed to work. It only misfires for about 30 seconds to a minute, only when driving, and then corrects itself. Im thinking it might be a vacuum leak or problem with the injector.
Also the ignition coil and spark plug where oem. Bosch and NGK.
Let me know what you think ?

Maybe you should try to change all of them.
