I have experienced constant power loss when driving the car on petrol to the point it will just crawl. Then when LPG is selected the car takes off and I cannot fault it. I have changed the spark plugs and have also used a fuel additive to see if there was a blockage, but to no avail.

The vehicle is automatic so when petrol "default" started it sounds a bit rough then settles down. When moving slowly the car it seems ok, but as soon as you wish to increase speed it just won't accelerate no matter how hard you depress the peddle it just wont increase speed, however once the LPG switch is selected I takes off. Any help would be appreciated
