My 2011 Kia Forte has been have some rough acceleration. Kind of a rattling noise. I was hearing a gurgling noise And a small acceleration noise so I drained radiator and changed the thermostat also cleaned the throttle body the gurgling seems to have gotten better but the rattling is only getting worse. Idk if it’s just that it’s hot outside but it also seems to have a high temperature but no over heating. Since there isn’t a temperature gauge idk how hot it’s running. Please help!
