Hello every one
I have an subaru xv 2.0i 2015 cvt. Converted to lpg.
The car is jerking when moving from full stop.
If i disconnect the battery and reconnect it drives perfect for a day or so.
And than its jerking again when its about 1500rpm and moving from full stop.
When is write jerking i mean the car is jumping ...
I did the throttle relearn. And its the same.
I can not figure this one out and neither the garage.
May one of the computers in the car cannot calibrate it self that wich one?
I replaced the cvt ecu and it did not helped ... If some can pin point me to a solution i will be extremely happy thank you!!!

It's going to be hard for anyone to pinpoint your issue or issues as you have a large 3rd party add-on... the conversion to propane from gasoline. The only people that may be able to help is whoever installed it and manufacturer of the conversion kit.

Having said the above, can you clarify what you mean by jerking? Do you mean that the engine seems like it's going to stall? And if you press the accelerator down to increase the RPMs, the jerking goes away?

Well if it was an lpg related problem it was jerking only on lpg. But it dose this on gasoline as well.
No rpm play just when car start to move from full stop there is a jump like as if clutch was released by not well trained driver.. in my case its cvt .. so no clutch just the feeling of the car jumping forward.
