89 f150 running bad
it fires idles and drives great for about 10 15 miles then about half throttle is all you got.try to pull a hill or go more then half throttle it falls on its face and back fires.let it sit a few and ir runs good again.42 pounds of fuel pressure while reving it.did not have the fuel pressure checked when it was it messing up.any ideas?
