i just fixed a cylinder 4 misfire and i’m noticing this noise now, nothing from too just underside i hear a slight tapping/ this noise lol thanks for the help in advance!

i been having weird almost misfiring feeling for a few weeks intermittently but on my way to work today it just started feeling like the engine was jerking and jumping and now i’m hearing this noise:/ i hope it isn’t knocking im thinking bad catalytic converters but im not sure yet no cel maintenance on point at 191,200 k miles
