Question about 2006 Hyundai Sonata
Ok did the knocking noise speed up as you pressed the pedal? if so id check the oil first and see if that helps at all and if it continues to make the knockin sound you might have a thrown rod/piston. The oil can effect the the pistons being as it is the lubricant for the pistons to move up and down in the bores(cylinders) but the low oil would only cause the engine to start knocking if there hasnt been any oil added as needed for a long while. has you engine got hot or warmer than usual? the could also be a symptom of low oil.
