Looking for advise on the following issue please.
The car (960 3ltr estate with tartareni single point injection installed in 2000) generally runs ok but sometimes the following occurs From a cold start on a morning, the car runs ok for about 2/3 miles then starts running erratic. After a few miles it settles down and is ok for the rest of the day This is not consistent as some days there is no problem. I have not had the problem when running on petrol and also during the erratic running if I switch to petrol there is no problem that I am aware of. I have changed the injector top & bottom "O" rings about 2 month ago to rule out loss of fuel mix as the engine is warming up. Any idea's Thanks Paul |

It sounds like it could be the vapouriser starting to freeze

Single point will most likely be starting on gas with petrol only as a back up.
Tartarini vapourisers are know for blocking up waterways and suffering these kind of issues |

It is most likely down to lower temperatures reducing gas pressure in the tank , combined with less available heat in the evaperator . LPG powered forklifts also suffer a similar problem at this time of year , the are left in a warm location after a days work , so the gas evaperates to replace the gas used . Then when they go outside working the lower temp reduces the ability of the gas to maintain pressure in the tank & so you get a lower flow of liquid to the evaperator . Another & often overlooked problem is that LPG can actually leave a brown tarry gunk in the evaperator affecting how it operates , stripping & cleaning the evap normally cures the problem same as cleaning a carb or or fuel injectors . Be careful if you dismantle any parts of your lpg system as you may end up with a gas leak , liquid or vapour
