Hi, I have an 87 bronco II,2.9, 4w, 5 speed manual that starts great but wants to die for the first minute or so. Any suggestions? Thanks

 

Welcome to FTE!!!

I would start by checking the fuel pressure, pulling the codes and any basic maintainence, theres infomation about this in the tech info thread.

 

I've seen a TSB that describes this problem. If Ken00's suggestions don't yield anything helpful, clean the IAC valve, throttle body, and the upper intake manifold.

 

Mine does the same thing, i'v had the iac off and cleaned it, put almost a whole can of intake cleaner through the throttle body, changed the plugs, cap, rotor, wires, coil, fuel filter, and even the tps. (not all because of this problem). I'm thinking now It's a vacum leak i cant find or either the fuel pump or the fuel pressure regulator.

 

The fuel pump is in the tank on a 89, regulator is on the drivers side fuel rail, it has a vacuum and two fuel lines going to it.
