Ok working on this 1989 toyota 22re 5speed and 4x4. When started in the morning it runs smooth but as soon as it gets a little heat in it, it starts to miss. It gets worse while warming up and eventually will die but start right back. No water in oil or oil in water and no smoke. Any thoughts?

 

is it using any coolant? If so, head gasket. If not check intake and carb seals. And maybe post in the correct forum? lol this is 84-85 SFA trucks section
