kpfriar Posted November 2, 2023 Report Share Posted November 2, 2023 Not had this Lupo long. About a week. Shortly after we got it check engine light comes on, and seems to flash sometimes when idling for a minute. checked codes and I'm getting 16684 and 16687. (Misfire on 3, and ‘random cylinder misfire’). I’d look at plugs, leads and coil pack but I can see previous owner has had them all changed at end of June… im guessing they were changed due to a similar code or light. looking for a bit of advice as where to look at first. cheers.
