My brother has a Ford F 150 automatic, 5.8 liters and he is having a persistent problem.
Which surprises me because he knows A LOT about mechanics, so it's not often he is puzzled by an engine problem.
The truck is always stuck in high RPMs. He already checked everything. He changed the throttle and all the vacuums and it's not that. He has tried everything he has been recommended all over the Internet and the problem doesn't go away.
The last thing to try is a new computer, but it's kind of expansive and he would like to check all other possibilities before buying one.
Maybe someone here can think of something that could be causing that problem?
