98 Ford Ranger



Hi - My son has a Ford Ranger - He has put a lot of money into repairs, including a new engine, but he is still having the same problem.

He said that when he reaches 35 mph, the engine starts making noises - [He is in another state so I cannot be more specific…] He is a student and is so frustrated right now… I am just trying to start somewhere to get an idea, before he sinks even more money into it, if it is some “obvious” problem that the mechanics just are not getting to…
