Hey guys I have a 1988 f-250 with a Mazda 5 speed the truck starts up just fine and runs great while. Old. It on e it warms up the trucks start to stall out in traffic light and has random miss while driving? Has anyone had this problem also I get a smell that the truck is running really rich on the truck warms up

 

When is the last time the truck had the plugs/wires/cap/ and button replaced?

 

About 3 years, or some 25k miles truck is not driven that much
