Random misfires all cylinders

[christianbrown1996]

Hi guys,

My vagcom is reading misfires on cylinders 2,3 and 4 on 15-20 minute drives, in the region of 1-3 misfires per cylinder.

Is this a cause for concern or normal behavior for a car with 134000km (2011 plate)? No check engine lights or poor driving experience.

Thanks in advance.

I would start with plugs/coils, have they ever been changed?

Just changed coils. Changed one spark plug recently as it was covered in black soot. Still getting a misfire count on this newly changed plug. Haven't changed the others yet.

My GTI (115k) is doing the same thing, all cyl's misfire, but I do have codes and CEL. Will be confirming today, but #3 fuel injector
is stuck open according to shop.

this happens to my GTI too... no CEL, no other issues.

NEW ignition coils and plugs. Carbon cleaning done last year. New fuel injectors as well.

I ignore it now and I don't run live data reading using the BlueDriver app via Blue Driver Bluetooth dongle.

Yeah - ours registers a couple during warm up. Not bothered by it. Could be injectors getting old.
