Hy,you change filter GPL original?

[dtip]

yes , when this happened first thing we changed was filter but it was still same.
Also car drives a bit better now and this is happening just occasionally so we are thinking that maybe lpg gas was a bit bad...Gas tank was filled from almost empty to full on same petrol station...

Hy,LPG no its good,or spark its broken.
