Hello everyone
I have a 2003 JEEP KJ 2.4 Gasoline+LPG system.
When I drive the car, it doesn't have enough power, it jerks , and when I take it out of gerar and leave it in neutral, the engin shuts off.
I've already replaced the brake cylinders, spark plugs, spark plugs wires and the 4 intake manifold gaskets.
Any idea what it could be?
Thank you!

I never heard of gas + LPG. Air or fuel. You did plugs and wires. Dirty fuel injectors, vacuum leak, air filter. Those would be next for me. Mine seemed to be the CAT converter and Cataclean helped. I also switched to premium gas which helped. I have used SeaFoam in the past to clean the injectors. Coilpacks- did you change those? or just the plugs? I would check a service manual if you can as your vehicle setup is different than the typical gas ones here in the US. Do you have a code with this?

Any fault codes? I'd guess an inlet air leak.

I had a 97 TJ that was doing this and it was my TPS (throttle position sensor) malfunctioning. Not sure if a cam or crank sensor could be doing the same thing on your KJ???

I'd guess he is in Europe, gas conversations were popular a few years ago, not sure what its like elsewhere but LPG filling points seem to be disappearing in the UK, talking to people who had the conversations valve seat recession was an issue even with cars suitable for unleaded.
A shame because it was way cheaper than our overpriced fuel.
