The U codes you can ignore. The P0303 means you have a misfire on cylinder #3. More information would be needed to make an accurate diagnosis.

Possiblities include, but are not limited to: a bag spark plug, ignition coil, fuel injector or sticking valve.

Multiple engine codes PO300, PO303, PO306. what is going bad on this 2005 kia sorento?


I've had similar issues. The fix I used was to take my vehicle to AAMCO and let them run a diagnostic check. Most often it will be at little or no cost and, if you don't want to mess with the fix anymore, they can fix it onsite.

The engine light on my 2005 Equinox is in,


The check engine light comes only when the computer control unit (called the PCM) senses a fault in the electronic controls of the engine and/or the emission system, there are about 200 possible faults that turn the light on, to know what has developed a problem you must have the system tested, this is called an OBD2 fault code test, Kragen and Autozone parts stores do this testing for free.
