I have a 96 Ranger with ~150k miles. I know that one of the cyclinders
is losing pressure, but I don't think that really explains the sound.
When I am moving over 30 mph and give it more than half throttle in
any gear(has the Mazda 5 speed), it starts making a sound like a turbo
spinning up. I know for a fact that there isn't a turbo in it, and I'm
sure it isn't the gearbox or clutch. When I am moving slowly or
stopped, the sound disappears. Any ideas?

I know the catalytic converter is starting to go, but I found the
problem. I noticed the engine noise is getting louder and rougher, so
I checked the exhaust system. Exhaust hole. I got some tape to patch
it up, hopefully I won't get pulled over, since I won't be able to put
it on for two days(work).
