I am sorry I meant to say cooling for example I drove and the temperature use to drop to cold then at idle it return to normal that got fix then last night the cel come on made back home and went to sleep then this morning I turn the car on no light drove and it felt somewhat normal then I pull the codes and got 15 (ignition output signal) then 43(fuel supply system ) I been reading about the subject all day and no one seem to have a solution
