Question about 2001 Ford Ranger Regular Cab
I've got an 2001 v6 4.0 that i have just recently purchased, and already have had the tranny rebuilt, but am now noticing the truck lurches just a tiny bit while idling. The truck seems to be running strong, as i just got back from driving it a couple days in Baja, but this erratic idle is annoying. Is this indicative of a vacuum leak? The truck has a about 111k miles on it. thanks.
Any codes? tune up, dirty throttle body.fuel filter air filter.clean fuel injectors add some fuel cleaner.

That's where I would start. Get a spray bottle with water in it and a few drops of dish soap just to make it sudsy. Start the truck and spray around all of the vacuum lines, intake manifold, etc. If the idle goes up, that's your leak. Good luck

Ther is a air Idle control valve located on the side of the throttle body. unplug it remove it spray it and clean it with carb cleaner replace it plug it back in and you will be a Happy person again.

MIGHT be the tps
The TPS is sensitive to heat, moisture and vibration leading to the failure of some units. The sensor is a sealed unit and cannot be repaired only replaced. A TPS may fail gradually leading to a number of symptoms which can include one or more of the following: -

The P0420 code is a Catalytic converter efficiency code check the compression.Swap the #1 injector to a different location to see if the code follows.Test the coilpak. A cracked exhaust manifold is the most likely cause p0171 and 0174 Induction air leaks, vacuum or some kind fuel restriction, weak fuel pump, restricted fuel filter etc.You also could have an exhaust leak near the upstream o2 sensor. If youtake it in they will probably use smoke to find out where the leak is.

Check EGR valve this controls idle speed it might have carbon build up hold the valve open. All so check fuel pressure.

Have you replaced the timing belt? if not i would highly recommend doing so. these cars need to have the timing belt replaced before it breaks otherwise it can and will cause major engine damage.
