QuestionHi John, Although my car isn't a Land Rover Discovery, it is a Rover so I'm hoping you can help. It is a Rover 620 Automatic 1995 model. It has a 2 litre engine and runs on petrol as well as LPG. It has had 9 owners including myself and the LPG conversion was done by the 7th owner through an LPGA approved installer. I have had the car almost a year now and the car was running perfectly until about 4 months ago. What happens is that the engine stalls when the temperature gauge has not reached it's normal position. When it first started, it would stall when the gauge is just halfway to the normal position. Now it has to reach normal completely to be sure it won't stall. I can drive it when it is cold as long was I put it on neutral when I come to a stop. If I try to drive or reverse too slowly it will stall. This past couple of weeks it has become worse because I am having to turn the ignition twice because when the engine comes on the first time and I rev it up, as soon as I let go of the throttle, the rev goes down, I hear a loud bang and then the engine just stops. A month ago it just would not start on LPG, so I was running on petrol for almost two weeks until I got that fixed. The problem was that the reducer for the lpg was damaged and had to be replaced. The mechanic charged me £130 for the job. I was hoping that the stalling problem would be fixed as well but alas no, and the mechanic who fixed my lpg problem could not work it out. Do you recognise the problem? Any help is appreciated.
Cheers
Raz
AnswerHi Raz,
you are very brave. I don't know if I'd ever buy a converted LPG vehicle. Nice Rover - perhaps that's why.
Here's what I've found for you and I hope it helps...
Converted LPG vehicles: Running on LPG
Once your LPG system has been fitted, your car will be able to run on petrol and LPG. Please observe the following operational procedures:
It is important that the petrol tank is at least one quarter full at all times in order to prevent any damage to the petrol pump.
Use petrol occasionally as it should not be left in the tank for longer than three months as it may become stale.
Vehicles fitted with carburetors should be run petrol at least once a week for 2-3 miles to keep the petrol system operational.
With petrol injected vehicle the engine will start on petrol and automatically switch to gas if the control switch is in the GAS position.
With a carburetor system, if starting on petrol, start the engine with the switch on the PETROL position. Once the engine is running, move the switch to the CENTRAL POSITION and continue to drive the car until the petrol in the carburetor runs out. Then move the switch to the GAS position.
It is possible to start the car in the GAS position, although a longer cranking period may be required.
