P0303 is a cylinder 3 misfire. If this is the only code pulling and you have changed out the ignition coil, check to make sure you didn't get a faulty coil or plug first (this can happen with any part dealers parts, even brand new), if the coil and plug are both in good condition, have a trained professional perform a compression test to check your cylinders
Information for code PO303 is listed in the link posted above, simply copy and paste the link!
