My car is on gas. I usually start up using petrol and when the engine's warm I switch to gas. I usually rev the car up to 2000rpm before making the switch, however it stalls when switching to petrol and I have to ' restart' the car. I runs fine onces the switch has been made though. Anyone knows whats the problem? Does stalling erm spoil your car? Mines a mixer.

How long do you take to warm up. I usually wait until the temp goes up till the middle.

try cleaning out your throttle housing and IAC valve, 8 times out of 10 this fixes stalling problems.
