Sounds to me that you might have some water in your fuel line. Change the filter, and shop at a station that uses fuel that is approved by top manufacturers. Not forever but at least until you figure it out. Exxon guarantees 5 tanks or something to a cleaner engine. Finally, it could be your injectors. Might want to get a couple of bottles of gas dryer and some injector cleaner. Cheap fix if it works. Oh, one more thing. The sonata is designed to run on 87 octane fuel, so using fuels like the premium might be causing problems, or even more so, you might be fueling at a station that uses more than the 10% of ethanol. Good luck.

Sputtering rpm filter


It probably doesn't like that ethanol in the gas. Try some medium or high test.

Rough idle, sputtering like its outta gas but it aint.


Could be a vacuum leak as it falls off under acceleration and does not play a part then. Check for broken or cracked hoses.....
