No codes relating to the misfire, I have had eml flashing at me a few times but just in lpg. |

suspect your lpg system is not set up to optimum and needs a service/calibration

Car has done around 20-30k on lpg. It had a flash lube system and I believe 10% petrol injection. I did think it could do with a lpg tune up but would be nice to get rid of the misfire on petrol first.

Check for leaks on the flexi pipes from the LPG injectors to the inlet manifold. They tend to stiffen over time and don't seal as well. To be honest it normally smells of LPG too if they are leaking. |

Plugged in to day and seems to be miss firing down one side more than the other. Did think about ordering a couple of coil packs and trying to change a few around.

Could be a possibility that the sensor is on its way out or the timing is slightly out on that bank after the rebuild. Try swapping sensors across banks if the problem moves to the other side you will have nailed it (thats if they are not lh and rh parts) |

Sure I've read about this problem on USA Jaguar forums, they are the place to look at for the 4.2 and 5.0 supercharged engines as there are loads over there...
