Hyundai Accent LC 1999 P1128
Hi all, i am new to the group and i am sick enthusiast for Hyundai. I own Hyundai Accent LC 1.3 62kw 1999. I bought the car new back in 1999 year direct from Hyundai dealer. Till today, i can't say any bad word for her. 20 years of revving and high speeds and all stuff and the engine still runs like charm like new. But i have one question. 2 years ago i added LPG system because here in my country the LPG is very cheap to buy. Gasoline is very very expensive.
Now the problem: When i drive on LPG the check engine light will flash with Error P1128 - Long Term Fuel Trim Multiplicative System Too Lean. If i drive on gasoline the problem will dissapear but as soon as switch back to LPG the problem will come back. How can i solve this because it's really annoying. I understand the electronics so feel free and write if there is any electronics solution to this problem.
And two more questions:
Does P1128 error reduces power and mileage or it's just information error ?
Does your Accent yurn oil ?
My Accent burns oil from the date it was bought till today and values are the same after 20 years. I try with Castrol, Valvoline, Motul, Aral but same result - In city driving burns 1 liter per 1000km and on highway sometimes burns very little oil, sometimes it will not burn any oil.
Thanks in advance to all people for answers !

The lpg system is connected to ignition coils, fuel system, O2 sensors and but i don't think they remmaped the ecu or stuff like that because car is 1999 year and i don't think the ecu supports functions like that. But if it supoorts, can i make some changes ? Because in my country, 80% of the mechanics are without needed knowledge.
