Hi guys,
Anyone got experience diagnosing (and fixing!) a cylinder misfire? I have a 2014 Cupra Mk3, remapped (by Revo) to stage 1. I always use Shell V-Power.
Started a few months ago. Got the P0304 fault code, local garage changed the ignition coil on that cylinder. Spark plugs had been done a few months prior. It came back after a couple of months. Symptoms were chugging, rough idle, EPC and engine warning light. Took it to a specialist and this is what they did:
The fault came back after a month of them doing this, attached is the OBD read out of what it found.
Before I pay more for them to keep investigating, anyone seen this on their car? Any advice appreciated! Many thanks.

Symptoms were chugging, rough idle, EPC and engine warning light. Took it to a specialist and this is what they did:
- Compression test which was all normal
- Removed and checked cylinder 4 top manifold
- Cleaned the injectors in ultra sonic tank
- Moved injectors and spark plugs btwn cylinders
The fault came back after a month of them doing this, attached is the OBD read out of what it found.
