As you can tell by the title I’m experiencing an intermittent misfire and some pulses, pops, and chuffs from the tailpipe at idle. I just changed my plugs and coils packs and that didn’t fix it. Anyone else experienced this issue and found the problem? Flashing CEL every time it misfires, but only been able to pull codes from it once showing cyl2 and 8 misfiring. It is catless and untuned.
EDIT: Well, turns out I’m a dingleberry, spent over and hour checking everything in the engine bay and noticed a fuel smell at cyl5, sure enough the plug wasn’t fully seated. She’s running like dream now

Here a cold start of my catless h pipe s197 with corsa exhaust(not sure the exact exhaust) does it sound healthy?
