Stalling when engine is changing between cold and hot EFI 1.3 petrol-----FIXED-------------------------------

Hi,

EFI 1.3 year 2003 hi jet. Petrol and LPG. Problem is a stall when engine is between cold and hot. It does it on both Lpg and Petrol. It will stall once then is fine. Idle is a little bit rough. Have changed plugs and air filter, oil is clear.

When warm no problem at all. When cold runs a little up and down but does not stall.

When it is warm idle is better but not perfect. Any advice would be greatly appreciated...

Would it be the automatic choke or a proper tune up? It says in the book tappets should be adjusted warm. The engine sounds a little tappety compared to years ago

I want to get this sorted before it gets worse. My hunch is it needs a proper tune up?

Thanks again, Chris.
