what maybe wrong with my 2000 ford mustang v6?
it starts up and idles high then it cuts down and dies and if u get it on the highway it will run gud for a min then start cutting down and has no power and back fires badly i have replaced my mass air flow sensor twice, my spark plugs and wires, manifolds , fuel pump and filter and it is still duing the same thing
Check air filter and replace if necessary and clean throttle with throttle body cleaner add Seafoam Fuel Injector cleaner to gas tank.
also check for vacuum leaks.
