Just tuned it up (looks like for the first time smh) the old plugs were burnt out and gapped 60 over i replaced with msd wires and delco pro platinum plugs. Ever since then it’s making a lul lul lul lul sound near constantly. I’m not sure what’s wrong. It never made the sound before and I don’t want this to be the end of my burban she has 305k on the clock but I was hoping to get another year out of it please someone just tell me it’s going to be okay lol or what to do. I’ve uploaded a video of the noise. Only check engine light is for o2 sensor which was on before the tune up. Could this be the culprit? Even if it it’s getting changed this weekend.

I would start with checking the plugs. An spark plug wire connections. Easy to crack a plug. How’s it drive?
