508 1.6 gas cutting, late reaction to gas

Hello, I own a 2012 model 508 1.6 VTI automatic vehicle. I have the problem of cutting off the throttle both in vehicle departures and departures and in gear shifts. I also feel the gear shifts excessively. Although I want to accelerate suddenly, the vehicle accelerates after 5 or 6 seconds, which also creates sudden security problems. My question is, lpg and petrol have the same problem, what could be the reason? It is assumed that the gasoline does not go too late and it does not go to the LPG. Reformist2020-06-21 09:41:40
