How to Fix a Rough Idle on Ford Explorer! PCV Vacuum Leak $5.00 | Ranger | EVAP 

This would have to be the best video I have ever seen on fixing anything. The audio is clear including description on the screen in words, very nice. The camera shots are perfect, easy to see. Just all around great video. Thank you.

Thank you so much for this video! I am a carpenter by trade only know a little about mechanic work, such as oil change, tires, brakes etc... so when my 2002 ford explorer sportrac started Rough idling and cutting off while idling, Naturally I took it to a "mechanic" to get it fixed.... smh, that was 4 months and 1400 dollars ago!! I have been to 3 different mechanics and replaced the MAF SENSOR 3 times, cleaned throttle body with sea foam twice, as well as changed plugs and wires and vacuum lines... the list goes on... yet my truck has the same exact problem it had 4 ms ago. so thank you so much for creating this video so that a carpenter like me could fix the problem.. lol, smh, my next step was find the ' mechanic work for dummies' book, lol. Amazing that 3 different mechanics did not realize it was a 5 dollar hose! SMDH...Thank you again

Great vid! Short and to the point. I changed my Ranger 4.0L PCV valve on the back of the driver side valve cover and ~3-400 miles later started having a rough idle while in-gear waiting at traffic lights. Quick youtube search - and this was the solution. Quickly found a Dry-Rotted Elbow (crack/soft spot facing down to the engine) headed to Autozone first thing tomorrow to sort this out. Thanks!

I might do this exactly 5 years after you did this. Still valid video today and years to come, sure of It.

Thank you for sharing your knowledge 🙏

Great video to a simple fix. Thanks for the knowledge. You just saved me $400-600 dollars from the rip off mechanic.

I added some Amazon affiliate links in the description, if you will click through them to buy parts for your project I would appreciate it! It helps me make more videos! Thanks!

Thanks for the updates... It’s very informative

Great video and great camera work

This also applies to a 4.0 sohc ranger

This is really useful to see thankyou. I didn't know this could be the problem or how to fix it. I'll give this a go! Thankyou, your video and presentation is very good and clear and nice to watch.

Thanks for the info

Thank you for the video.

If you followed the plastic tube to the back of the engine you'll see a rubber elbow hose that should be checked for cracks, then further follow the tubing behind the engine, it leads to another rubber elbow hose you should check too for cracks. This last elbow there is connected to the PCV Valve. That PCV Valve if not disconnected properly can crack the plastic port at the rear of the driver side valve cover. That's a lot of dollars to replace. I know, because of a carelessness of a mechanic, that valve cover replacement cost me a lot of money. That PCV Replacement should be done by a technician at the Ford Dealership, they know how to do the task properly.

What is that connecter at the top left of the screen??

Is this the same ubication of the pcv valve??

Nice video. Thanks for the info!

Thank you for the wonderful video, perfect audio and description and awesome camera angle

Thanks very helpful

Nice. I hope this is whats causing my rough idle. Can't wait to check.

Your engine is very similar to my 4.0L engine on my 02 Ford Ranger, XLT, so I'll be checking out this hose being my truck is 19 years old, but very well maintained. That's for the tip.

Thank you for this help.

Does pcv valve cause a burning smell

What’s the thinner hose right above that one

Thank you,,Really appreciate your advice,God Bless you 🙏...

I had a bad O-ring on the PCV valve fitting where you connect the hose to the nipple. I used a smoke machine to introduce smoke into the intake manifold and the smoke leaked out around the nipple The result was a vacuum leak that I was able to repair with a $0.50 O-ring from NAPA.

Thank u u had help me out alot I had this same problem

Quoted 23.09 at Ford and was told if heated pcv it's over 50.00 for a pcv.

thank you bro 👍

Just wanted to say I’ve done my spark plugs and all three 02 sensors on my 2002 ford ranger edge it’s a 4.0 L V6 but this is exactly my issue thx again

What year is this vehicle? It looks nothing like what I have.

Rough idle, wants to seize or stall at intersections. Im going through the motions of finding the problem. Already did an oil change, cleared any potential water from gas tank, my next step is to check pcv valve. I really hope this is the issue. Your video helped me gain a better understanding of what to do and what to look for. Thank you

I found this at Autozone under Dorman PCV Valve Hose, # 46032. It will be checking this to see if it is the problem on my vehicle.

So my ranger had a high idle I replaced the IAC valve , TPS sensor Cleaned throttle body and maf I just now seen this and check and I believe my hose like in the video is gone bad

98 explorer v6 sohc 233333 miles, exact same issue, collapsed hose going to pcv value. idle from 700 to 500 at stop lights, rough idle, up and down rpm only at idle. happened after value cover gasket job. unfortunately i replaced iac valve and dfpe first at $137 . Finally the vehicle rough idled in my garage and I found the collapsed hose after months of hating stop lights. then i found this video. thanks

great video, what year Explorer is that, and is it the same fir SOHC engines?

I have a 1998 explorer sport. It's a 5 speed. If I Rev the engine an get off the gas. It acts like it wants to stall. Rpm's drops low to a point almost chokes out. Thx for the vid an the info

That’s what mine does on startup shakes really hard, makes a slight whistling noise, and has a jolt on acceleration.

My 04 has a hissing sound when I accelerate and now it is barely accelerating when I first shift to drive could a vaccume leak be the cause?

Can that tune also cause air and fuel ratio problems?

Would this issue cause MAP sensor or Fuel pressure regulator sensor codes?

Is there 2 diff set ups? My 96 looks nothing like this

I hate those GTH clamps. I always replace them with regular ones so I can use an5/16 socket in the future

Why does my 2004 ford explorer sound like a monster truck idleing and shake like hell? Some one please help

Is that snow?

Wht year is the explorer

Stick a rag in the oil fill tube so nothing drops in there.

I own the SOHC too great engine

Think the whole tube is only 20 might as well change all of it on this old of a vehicle

TWO WORDS... tin snips... also sold at Auto Zone

I’m pretty sure that’s a ranger, the explorer intake is different, alternator, valve covers….

First thing... Check your Spark Plugs & Wires. One badly connected Plug will cause this too.

Yes, I expected to see blood.

It's a hose no tube

A good prayer: I'm a sinner JESUS please forgive me for all my sins I know you shed your Blood for me on the cross at Calvary. Thank you JESUS for my salvation and for shedding they Blood for me. I love you JESUS. Romans 10:5/10 ct...❤️k JESUSisLord!Amen... Amen.. If you'd like to call someone who cares 83.for.truth... Ok....

Read about what JESUS did this is mine blowing. Can you believe this, did you ever hear of this about HIM Romans 10:5/10, c u there $$🧐yeah..👍
