accelerator promblem or not?

[loxman]

Hi everyone,
I have a 2002 3.0i e53 x5 on lpg. When i start my car and go to accelerator engine cuts, out thought something to do with lpg but when i switch it off and run on petrol still seems to do it. does it 3 or 4 times then drives ok. Anyone have any ideas or same promblem. thanks.

Sounds like the lpg is out of tune. This will throw the injection trims out which which will make it bog down when you switch between the two as the engine ECU has to make adjustment. Run it on petrol only for a while - including a few cold starts and seee if its better.
