Ford E-150 1997 4.6L v8 255000 miles
Can’t seem to figure out the issue. Starts and runs, sometimes bogs down when you go to take off. Going uphill, speeds slows down although hitting acceleration. But then will be fine on flat land. If I drive around for like 15-20 mins, shit it off to go into a store, it won’t start...
Changed the idle air control valve, sparks plugs and wires changed, Egr changed, no vacuum leaks we can find. Oxygen sensors changed.
