I took it in to my mechanic and he replaced the fuel filter, which he said was completely clogged. This didn't seem to help at all. He checked the catalytic converter, and he said that was fine. He also tested a few more things that showed a bunch of different pressures were fine. When he hooked it up to a computer nothing came up. I changed the air filter recently, and on reexamination that seems fine. The truck was running great before this and was previously owned by a mechanic. It seemed like theproblem occurred all-of-a-sudden. My mechanic said he doesn't think the problem will leave me stranded and that it is probably just a "tired engine" but I don't know if I'm willing to accept that answer. Everything else about this truck is great and even with the high mileage I think it has a lot more left.
Two things he suggested were changing the spark plugs (which aren't awful, but also could stand to be replaced) and the u-joints (to get rid of the rumbling, which I'm not as concerned about as just getting the power back). Could the spark plugs be what is causing the lack of power in 5th gear? Since there are 8 spark plugs (on a 4-cylinder) and it's very labor intensive on a Ford Ranger, it is going to be expensive to do that, and this truck is more or less just used to haul light loads of things from time to time. Not something I want to invest a lot of money in, but also enjoy having as a second vehicle.
Could it possibly be the fuel pump? If so, is that an expensive fix and/or worth it on a truck of this age?
have the same problem?
