Difficult Problem
Okay guys I have a challenge for any of you looking for one. My truck has been doing this since I got it and I can't figure it out. It's a 2000 Ford Ranger XLT 2.5 5Spd. It runs fine if you dont rev it above 2500-3000 rpm. After you rev it that high coming down to idle it is stumbling real bad and sometimes stalls. I've been driving it like this since I got it, and it does fine other than this. It gets better the longer you drive it, but it still will do it if you rev it high enough.
Here are all the parts I personally have changed (previous owner said he did the plugs and wires and air filter, which it looks like he did but I'm about ready to change them myself):
-Fuel filter
-coil packs
-timing belt
-egr valve
-cleaned throttle body
-iacv
-tps
-thermostat

Have you taken off the intake manifold? On the 4 cyl they have what is called a intake manifold runner. It is a set of 4 gates that a motor controls, to control the air going into the engine. The rod that goes through all of the gates sometimes elongates the guides and causes it to stick in position. I am not saying this is your problem but it is something to check. Also the video link doesn't work. Retry it so we can see what is going on.

My cheap guess would be pvc. That should be replaced every 60,000 miles on that truck. Also the 2.5 had issues with the connectors on the TPS which can cause the IACV to screw up. Might be worth your time to take some electronic cleaner and hose out that connector(s) on both the tps and iacv and clean it plus put a little dielectric grease in the connector to make sure it does not corrode up. There is a Ford TSB for extending those TPS wires but don't have a clue what it is.

Scan the computer for trouble code clues & post All code Numbers found.
Good idea on the video, but your last link doesn't work either.

There aren't any codes. And I'm not sure why it isn't working. You've tried copying and pasting it?

This is an OBD-ll system & with it running so poorly its difficult to believe it hasn't stored some codes, even if they're just pending ones, so are you saying you've had the computer scanned & no codes were found????
On the link, delete the m & add www in its place.

Yes no codes are found. The light has been coming on for the cat lately because there isn't one, but it did this before the cat was removed.
