Clio missing spark

[l0rd]

Hi all,

Just to add one more issue on my car

Car is a 1.4 16v 2002 model k4J710 engine

When running, you can feel and sort of hear that it is missing a spark but not every time.

Diagnostics show no errors.

Today i replaced 2 coilpacks made it a bit better but still the same issue.
Can someone remind me which coil packs work in pair?
ATM we replaced no 3 & 4, the ones away from the gearbox

What is next?
