F20B6 4TH Cilinder does not work

[Regis232]

Hi,
I have bought 1999 Honda Accord with F20B6 engine and LPG equipment.And I have to say,car is great.But on neutral gear,when engine is running on idle , there is big vibration from engine bay , and engine is running unevenly.I have disconnected LPG Nozzles one by one, and when I have disconnected 4TH cilinder nozzle,nothing changes.I have checked spark plugs and engine compression is fine.

How can I solve this problem?

What happens when you disconnect another nozzle from another cylinder?

Sounds like a faulty LPG kit not supply the gas to cylinder 4
