Popping coming from exhaust while idling

1. If it was the type of plugs themselves, I would think it’d be happening on both sides
2. If it was 1 or 2 plugs specifically, the sound would’ve moved around when I swapped em around

That’s why I said I’m not saying it’s 100% the problem but it still could be you can have them overheating a coil I’m not saying it’s the problem, but it still couldn’t be

I have/had no way of doing either. The cars at the shop now. Forgot to mention in my previous reply that I did check all the plugs gap, they were all at 0.028
