How to Diagnose a Ford Ranger Rough Idle

- In this video I discuss how you can diagnose your Ford Ranger's idling and rpm issue.
With idling issues the most common problem is an air-related issue. There are several easy things to quickly check to identify the source.
First, if you can hear a "sucking air" sound than you likely have a vacuum leak somewhere. On Ford Rangers the most common source of vacuum leaks is the "vacuum tree" on the side of the intake manifold. This tree has several rubber hoses attached and they frequently crack or fall off of the tree, creating a vacuum leak. Another common source is the rubber elbow that is located underneath the throttle body.
Other sources of idling issues include the throttle body butterfly valve, idle control valve, mass airflow sensor, and the air filter. - Auta a dopravní prostředky
You said the air filter looks good. Well you are looking at the back side of it in the video. Of course the back side of the filter will look clean. The front side is where it gets dirty, Really bad call on that one.
Thanks for the video, great info and presentation! Appreciate it! I'm also in NC, getting my 94 Ranger back on the road, same color blue! B-)
Thanks for your help.
great video ! looking for some advice on my 2000 ford 2.5l. i have a lean code, checked for vacuum leaks with a smoke machine. there was smoke coming out of the idle air control valve's(IAC) top/breaher cap/vent (not sure want its called), and on the Exhaust gas recirculation (EGR valve) vents holes . wanted to know if that was normal?
Had a recent problem with sudden prolific smoke. Its rare but it was caused by the transmission vacuum modulator sticking. It was attached to the exhaust and when it stuck open it sucked transmission fluid back up into the fuel mixture. It was pink fluid.
That issue is because the vacuum diaphragm was leaking inside that vacuum modulator. The valve is basically an on/off switch to tell the transmission you are putting a load on the transmission and react accordingly
i feel like your channel will take off soon man, very good an calm explanations.. i'll subscribe.
have 07 3.0 v 6, ranger have vac leak to temp control stuck on defrost to cool, where do I look? changed the flow direction behind glove box,
thank u
Another cause of a vacuum leak is the purge valve may not be closing properly. That's on the hose that you pointed to, where the elbow tends to crack and cause a vacuum leak. Sometimes it gets clogged with carbon granules from the carbon canister.
I guess the valve shouldn't be open while idle. (That seems to be part of the problem I'm having, currently)
Is that where he points to at 4:08ish
@@phatboitex2cali Somewhere in there. Twas on a hose coming from that black canister. But, my problem was actually the capacitors in the ECU. If you check the trouble codes, it'll give you an issue for the maf sensor, coolant temp sensor, throttle position sensor, intake temp sensor, etc.. All those at the same time.
It probably means that the capacitors are bad, and not those devices. Capacitors that regulate the reference voltage for those components.
I wish people would start and run the car to document the symptoms. I happen to have the same model, and it's surging and dying from time to time. It'd be really helpful for comparison.
Appreciate the effort though, Thanks for the check list.
Would the idle control valve cause the truck to seam like you have a stuck choke
Happen yesterday , my idle air control valve had a slither of a leaf stuck inside, also if you disconnect the wire it leads you to the problem.
Great video!
What year is your ranger ? Thank you 🙏
I'm suspecting it's all that duct tape man
Thanks alot man i got severe idling lol
I got ground to cover now
i guess it is kinda off topic but do anybody know of a good site to stream new series online ?
@Yehuda James I use FlixZone. Just search on google for it =)
@Westin Joshua definitely, I have been using flixzone for since march myself :)
@Westin Joshua Thank you, I went there and it seems to work =) I really appreciate it !
@Yehuda James glad I could help xD
Thanks
And how I replace or fixit ?
@ 04:12 slightly wrong description. That hose runs from the throttle body to the fuel canister, not to a "pump".
The purpose of the canister is this: It collects fumes evaporating from the fuel tank (while the car is parked) and condenses them back into gasoline. The car then sucks this excess fuel out of the canister and burns it while running. This eliminates the old problem of walking into your garage and smelling gas fumes from your parked car. In the old days, your fuel tank was vented to the outside, and the gas vapor could be detected after the car was parked a while. Now it is vented into that canister, and reused. so the smell is eliminated.
That hose is designed to flow the fumes and/or condensed fuel from the canister into the engine, so that it does not overflow. It often has a "purge valve" in the middle of the hose; such a valve is designed to purge the canister for only the first 5 minutes of when the car is started.
Wats up with all of the duct tape
So what if that hose at 3:55 - 4:15 is entirely missing
You need to replace it or you will always have a vacuum leak and bad running engine.
Hello I have a question here.
What is the black tube box tank with the tube connected ?
Where are the two connection points? From airbox (lower left, engine bay, as you look at it) to throttle body? If so, that's the intake tube.
It is the fuel canister. It collects the fuel that is evaporating from your gas tank, and recirculates it into the engine to be burnt. This is to prevent the car from always smelling like gas fumes because fuel is always evaporating from the tank.
the tape/foil on the vacuum lines look questionable
It dose not idle at all you take your foot of gas pedal it diesò
got a 2001 3.0 shakes alot and has gotten worse, happens at a stop or low speeds below 10 mph
We’re you able to find the solution? Have the exact same problem with mine
Me too any luck???

Help, my ranger is in danger, of being used as target practice...
I have an 01 limited edition Ford ranger edge. 3.0, V6, 5speed 2wd.,that I'm trying to restore and parts have Ben hard to come by. If anyone has any feed back on where I can look for parts ( engine, body parts among other things )would be very helpful. Thank you.
