3.8L random misfire problem :/

Was driving the Camaro to my grandpa’s house today. Was going up this hill right before his house and I noticed all of a sudden I randomly lost power, thought it stalled for a second, turned down my radio and downshifted. Something was deff wrong. Pulled it into his driveway and listened to it, idle was choppy as fawk and the engine was shaking a decent amount. I went and replaced the plug wires all around and pulled the EGR valve. EGR looked fine. I have no clue what this is. It isn’t throwing any codes either :frowning:
