Re: Need help with cold start issue.

Anything between -10 and +10 fuel trim is seen as acceptable so between -5 and +5 is very good indeed.

Re: Hot Problem

Hi Hugh,

It would make sense that faulty (or missing) coolant temp sensor could cause this. Let us know how you get on.

Re: Tuning Prins Vsi

True, but worth doing if you want the LPG side to run properly and at all rev-ranges (and to avoid any engine damage whilst on LPG and it cannot cope and runs lean).

Report back with what you decide to do.

Hi Nigel,

I am not sure about a non-CAT car but certainly on a CAT car there is no gas smell out of the rear... just standard fumes.

Re: Help please for new member!

Hi Nigel and Welcome! Firstly, surely the fuel tank can be repaired or you could source a second hand one? Some LPG systems do not allow you to run solely on LPG, some don't start well on LPG and if there is no petrol in the tank, some fuel pumps can burn out. As regards to the LPG installation, if ...

Maybe contact NGK UK direct for clarification?
