Air activator

good day my car 106 97 xr has now doubled fuel, the idle started to fluctuate, they recommended me to clean the acmometer but I could not see the acmimeter in my car, did not have these models or was dismantled and I would be glad if you give some information on how to get rid of this situation

my teacher air flow meter happens in diesel vehicles. see your throttle and idler engine

Thank you, do you have any other advice to restore the fuel, both traction has dropped and fuel has increased

One of the factors of throttle is my brother. Is there a lpg in the vehicle? Places to check if lpg

the vehicle has a lpg air filter new throttle and idler engine never looked like gasoline smoothly and the water has been set 7 times full gas in the last 2 months ha bide not sequential straight plugs setting is very good but not old fuel
