Hi all,
2015 R - Only seems to happen when the car is cold but under moderate acceleration I'm getting a misfire.
Occasionally it'll occur when warm but barely noticeable.
It was serviced last week with a fresh set of stock plugs so I can rule them out.
Nothing on fault codes.
I'm running JB1 but switching out to JB4 this week, is it time to treat it to a new set of coil packs?
If so, which is the best option? Latest rev golf, RS3 or R8? Doesn't seem to be much difference in cost.
Any merit in upgrading plugs at this stage too? Only mods are intake, elbow, Res delete and the JB
Thanks in advance
