It is always best to start simple on a lot of these things. This code indicates that somewhere in the evaporative system you have a leak that has set off the code. The gas cap is the most common culprit and that is where I would start. Buy a new gas cap and put it on. It may and should solve your problem. A lot of gas caps have rubber seals that do wear out over time. If this does not solve your problem simply use a search engine and type in p0441 a wealth of information will pop up. There are other possible causes and solutions but that's where I would start (with the gas cap)

Under the hood you will find a white sticker, about 2-3 inches wide. On it will have the engine size/group and the spark plug gap and other service information. Good luck

I had the same problem. I found out that the fuel pump was not putting out enough pressure. changed the pump and bam down the road I went.

we had a hyundai once, that stopped and started for no apparent reason , after much looking at and mechanics it turned out to be some butterfly or non return valves leading from the fuel pump to the engine. they were closing up and stopping fuel from passing through , might be the same kind of thing . hope this helps

They are directly below the coil packs (10mm bolts).
