I have a 2001 v70 2.4t auto on a Vialle LPi system

On petrol it runs well and pulls hard through the rev range.

I've recently replaced the plugs as a baisc service was needed and the car is new to me. Also because on LPG under hard acceleration I noticed it was missing and losing power.

Flashing ECU light. Turns out I've got a misfire on cylinder 3. Got 2 good used coils. Replaced cylinder 3 twice with known good coils. Still persists.

When accelerating on LPG and giving it full throttle it will bog and miss, switch over to petrol it's like turning on a rocket booster. So it has to be LPG fuel delivery.

Ideas?
