What is the diagnostic code P0302 on 2004 Kia Optima?
It sounds like you have a misfire on cylinder #2. My first thought is have the spark plugs been changed at all on your car? If they haven't, then a tune-up is probably a good place to start. If they have been replaced, you need to check to see if they replaced with the FACTORY spark plugs. If you use anything but the EXACT plugs that came out of it, the car will run rough at idle while in drive, and will misfire when put under a load like a hill or when passing. I had this problem except it was cylinder #4, with code P0304. I checked the spark plugs which had been recently replaced by the previous owner and sure enough, they used the same brand as the factory plugs but didn't use the EXACT plugs that came stock. I bought the more expensive factory plugs and the misfire disappeared. I don't know if yours is a 4 cylinder but if it is, it needs to have NGK Iridium plugs in it. They have a very specially designed electrode that is much smaller than most other plugs.
