i have a cuore 2002, it was running gr8 on CNG, 2.4-2.7 per km.
I expected it to go good on petrol, but when i switched, it had high rpm at idle. so i removed the air intake restrictor which was attacehd for CNG.
then it went good for a day, and now agn the idle rpm is high on petrol. it has new oil, oil filter, air filter somewhat 2 month old, two-pin plugs are new.
is it abt the fuel filter?
is it about the air intake?
air intake has two inlet holes, why?
usually in cuore the air inlet has a narrow duct also, which is absent in my case, so is it the problem? where is that air inlet narro duct goin to?
cuore doesnt hav choke, so how the tuning is done?
CNG times are goin out, petrol is basic need.. kindly help early
