FORD EXPLORER ROUGH SHAKING VIBRATING IDLE DIAGNOSIS & FIX

In today's video we take a look at my 2008 Ford Explorer w/ a 4.0 SOHC V6 engine. I've been noticing recently that the engine vibrates and shakes during idle. I don't believe it's a misfire. It seems more like a vacuum leak, however we don't have any trouble codes or DTC stored. Follow along and I'll show you how we can diagnose this problem by looking at fuel trim numbers using a very cheap affordable diy scan tool and a smoke machine.

Sometimes the shorter videos helps more than the longer ones for the beginners. 👍

[@Garth2011]

Smoke machines are so universal. A modern shop must have for sure.

[@expandedmusicgroup7205]

Thanks and glory to Jesus Christ for your help

[@Darjan_Spasojevic]

Dude you don't have to fix a vehicle that the parts cannon couldn't handle from other shops to help us. You're a great teacher.

[@rickrogers2649]

Love the fact that you always give a full explanation of the diagnosis and the fix. Great information Eric. Happy thanksgiving to you and your family !

[@jaredadams5194]

Best short explanation of fuel trims I've ever heard...makes more sense than the 20 minute videos droning on about trims. 👌🤘🤘

[@josephremache3721]

Short, sweet and to the point. Love your videos man!

[@jonmullaly7497]

Dude no need to justify making a vid! I look forward to each and every one of them!

[@HouseCallAutoRepair]

It was only through detailed explanations like yours Eric, that really helped get a deep understanding of fuel trim behavior.

[@rikkhaynes1391]

Fantastic video man! Love how EVERY video you give short but detailed explications about every step in your diagnosis. Keep it up man!

[@jimharper6073]

Thanks for explaining the theory behind the fuel trims... I will soon have time to check my vehicles to see how I stand

[@x01e]

Excellent video for any DIY mechanic. Great explanation as usual.

[@mtuhro]

Thanks for putting these videos together. I like to watch the problem solving skills, rather than relying solely on intuition.

[@CrazyPetez]

Very cool. The right test equipment and knowledge is the key.

[@73Bdiddy]

The key here is to read and understand the fuel trim numbers. Thanks for explaining it.

[@38911bytefree]

Good vid man, not only the fix but the explanation are super clear. I was afraid you need to take the engine again on this truck !!!!. You keep it nice.

[@danielhall2982]

One of the best descriptions I've ever heard or seen of a vacuum leak diagnosis on fuel trim excellent excellent video

[@passport619]

This is the most well versed and informative video on learning about fuel trims and diagnosing them. Thank you!👍

[@Roger-pw3zz]

You're a natural educator. Thanks

[@jgeorges3061]

AWESOME information short but to the point lots of people will benefit from this video if they know what is the meaning of fuel trims and how to read the data great thought process as always learning form the best thanks for sharing brother.

[@jamestobler8473]

Great job one of the best explanation of fuel trims I've seen.

[@arthurfricchione8119]

Eric you and family have a happy thanksgiving. All your videos teach us something. Thanks for sharing 😊 Artie

[@johnnyhernandez2790]

I love the way you explain everything, super helpful for DIY guys like me. Im subscribed!

[@noeygarza6522]

Eric, You're the man! Now going to test my Ford Expedition. I do have a smoke machine. Exact symptoms you have.

[@lolalexxx21]

my exact problem with my 99 explorer. great video, i loved how you explained every step you were doing, and the logic behind it.

[@v8motors.]

Good to get the theory behind long & short fuel trim strategy.👍

[@63mrl]

Thank you, Eric. You're a wealth of knowledge.

[@mft1284]

Awesome explanation and diagnosis. You explained live data to a tee. Spot on, I definitely think you enlightened DIY people. Not a big investment for your OBII. I have the luxury of computers. Definitely enjoyed the application of the smoke test. You did an amazing job catching the bubbling, most people would just replace the valve. If you have an endoscope it can be very useful in tight areas that aren’t visible, especially for mechanics like me that are vision challenged. Overall you earned a like and follow.🤚🇺🇸

[@404notfound.....]

100% makes sense!! Excellent diog video. 👍🌟

[@hondalude89]

Bro!!! Thank you!!! I've been looking for a portable smoke machine. Informative and helpful!!

[@bryantoth5249]

Well thought out and we’ll explained troubleshooting video. Job well done.👍🏼

[@jstraum5991]

Great video Eric! Pulling the curtains back on what the computer is doing is always very interesting and informative - Happy Thanksgiving!!!

[@codywaterhouse3518]

Awesome explanation of the diag. Nice work man

[@nanoahumada6393]

Thanks! Great video.I have 06 with the same symptoms.

[@on-site4094]

Eric looks like a professor wearing glasses 👍

[@jumpinjojo]

Let me fix this for you. When wearing glasses, Eric looks like a professor.

[@plead5th187]

I'm learning from d professor ..lol.. good lesson.

[@jamesrobinson2433]

I purchased a smoker last year and I'm having the same issue you described with your explorer. I just recently replaced a leaking valve cover and while i was at it i replaced the ERG value. So now I'm running much higher than the numbers you have. I have a 1999 XLT explorer with 256k miles on it. I so a lot of maintenance and have everyone tell me to just get rid of it until they ride in the car with me and realize it runs better than theirs. So now I'll pull out the smoke and see if and where there is a leak. That you for your videos as they provide a lot of help for guys like me who want to do their own repairs.

[@judih.8754]

Great explanation Eric. I like these short sweet videos. I ordered one of those scanners too. Just in case I need to troubleshoot before bringing it to a pro.

[@AMGTOM]

Thanks a lot mate for your videos, very informative and helpful. Keep Posting !

[@patrickkamya5224]

Wooooowww!!!! Thanks a lot. I've got more information in this one short video than I got in so many long videos. Now I am definitely purchasing the Kingbolen :D

[@mumbles552]

Sure glad I found this vid as I have the same rough idle problem in a '03 Explorer 4.6. New plugs, wires, injectors etc haven't helped much. I suspect a vacuum leak as it's periodic and the engine runs great and makes power. I suspect the plastic intake manifold but first I'll have to make a smoke machine. Thanks for posting this!

[@Djcoolmoed]

That’s awesome I have the same issue with a 2004 explorer. Got back from shop after a new head gaskets and timing chain it’s still has slight shake. Going to do this on my own have all the tools. Infamous 4L v6 so I was leaning timing chain. Paid $3600 for engine pull etc. Idle was worse. They also replaced intake manifold they didn’t charge for. Lol

[@OgunjobiDavid]

Thanks for your videos. They are really helpful all the time

[@marlinyoung1606]

Nice quick simple video man!

[@tankabbot22]

Nice video! I’m smoke testing my 07 Mountaineer tomorrow . Trims are about the same as yours positive! Thanks man!😀

[@dporrasxtremeLS3]

This was PRICELESS!!! Thanks!

[@MattyEngland]

Cheers for another upload Eric 👍👍

[@ADVANCEDLEVELAUTO]

Thanks for stopping by!

[@johnwilkerson2195]

[@amzngmo.e]

Keep them coming. I have the 07 version of this vehicle so thank you.

[@fredsalter1915]

Another fine video! And congrats on busting 100K!!!!

[@ADVANCEDLEVELAUTO]

Thank you very much!

[@mikechiodetti4482]

I ordered that smoke machine like yours. I'll be using it on my 06 Nissan Frontier 4.0L V6 for that same problem except the engine feels like it has a rumble like a motor mount that may have collapsed but does not shake the vehicle. Bank one has a higher than bank two LTFT. As always thankyou for this video, it is helpful.

[@roxanneabbott8424]

Cool video! Have a happy Thanksgiving Eric and your family too!!

[@frederick6008]

Thanks Eric, it makes sense now. 👍

[@joealvarado3342]

thank you Eric,extremely helpful

[@odishoodisho4904]

Great as always

[@markferraro5250]

Great job ERIC. I have the same smoke machine happy bird

[@tilt213]

Subscribed because i think you've nailed down this vehicle.

[@jamesrossmotors]

Great video. Just be aware that this video is only applicable to engines that use a MAF Sensor. Engines with a MAP Sensor only will not be affected in this way.as they will use the leak in the fuelling calculations. Hope this helps someone

[@luis140500]

Awesome video 👍

[@isalmankhan1]

Great work, Thanks for sharing Bro👍

[@mojobrown33]

Wow that’s awesome bro thank you for the information.

[@Phantomas2011]

BOOM SHAKALAKA!!! Nice job, love your videos!!! 👊 I’m dealing with an egr code 34 voltage too high in an oldie but goodie 1986 ford e-150 Exhaust smells rich… I’ll need to check the vacuum lines next, electrically the sensor and wire integrity checks out, I replaced the egr with one from standard! It’s smoke time next too!!! Very annoying can’t pass smog, and OBD1 🥶 can’t communicate with this beast….

[@paulwells4203]

Helpful video thanks. Shorter is better in this case.
