Hi everyone, I have a 88 f250 custom. I recently had the fuel pump replaced after it cut out completely on me one day. The truck starts just fine, but when braking, going down hills, or coming to a stop it seems to stall every now and then. Obviously I want this fixed before I start hauling things and become a wrecking ball on wheels. Any thoughts? This stalling problem started as soon as the new pump was installed.

 

Since I missed it in your other exact duplicate thread ... Welcome to FTE.

And as stated in the other thread ...

Check you Brake Booster for vacuum leak.

-Enjoy
