Ojisan (my old Galant) has decided he doesn’t like to start when the temperature is bellow about 25.

He starts but runs rough for 5-10sec before coming good. When its hot outside he startups fine.

The only other issue Ive noticed is that on hot days after the engine bay has heated up his idle is pretty low, around 500rpm when the AC switches off, its fine when the AC is on.

I was going to start with cleaning the ICV, but Im thinking this starting issue might be something else.

Anyone got any pointers for me ?
