Civic EG

ok here is the scoop my car is throwing no cels
but when it idles it sputters a lil bit and you here the idle drop some times it drops so low it feels like it wants to stall. also sometmes when iam driving it almost dies/bogs real low. and a mech told me the my fitv vale was stuck open could this be why or is it a fuel issue

could be fast idle valve or you could be low on coolant.

well it was low on coolant had to had some and coolate lines did have some air pockets. and corect me if iam wrong the fast idle runs off coolate and if there is air pockets could it fuck with the idle ???

it could possibly mess with the idle.
