Whilst driving my 2019 mk8 I’ve noticed the occasional misfire when accelerating. Anyone know what the cause could be? My car is tuned to 254bhp and 400nm
It could be a variety of things. I’d start by inspecting the plugs.
What does that even feel like?
Have you plugged it in to confirm it’s actually misfiring? I remember that early Mk8’s had a high-pressure fuel pump that, at low RPM, wouldn’t fuel the engine properly, which would cause hesitation or misfiring.
You can do some googling to see if that matches what you’re experiencing, but if it’s only just started, it might not be that. You can replace it with the later Puma ST HPFP, and apparently, it gives a better experience.
Bring it to my garage!
Take it to your mechanic!
