Oh how I long for the days of plugs, points, Carburetors . Life and engines were so much better in every way. Thanks for the great sharing of knowledge. Very good and informative.

How can anyone give this guy a thumbs down?! The cause and effect explanations are wonderful. YouTube has changed the world for the better and you are part of that. Awesome Dude!

Great instructor: detailed information on type and severity of vacuum leaks with differing symptoms, associated systems, causes, and tests to use. Awesome.

You're a god! Not only was this video incredibly informative and well-explained to someone (me) who is hardly a mechanic, but it helped my son and I find a leak associated with the PCV valve in his 1986 F-150 truck - the day before he goes away to school.

Awesome methodical explanations! Not just one sentence answers but explaining why and how each effect causes and effects other systems and simulating the problems! Thumbs up!

Man iv been trying to figure out my problem on this 2010 mazda 3 for almost a year now and watching your video helped me learn my issue is a vacuum leak. From me running it that long result in engine failure ? And i replaced the spark plugs and MAS sensor recently. Haven't found the vacuum leak yet but thanks to you i am now blessed with honest knowledge ! Much appreciated

One thing to mention for those who couldn't find a vacuum leak but idle is still rough:
Clean maf/map sensor, check spark plug gap and overall condition and check coil packs. The last is harder than the rest but sometimes even visual inspection can tell that they are busted: the core can look burned or wire connection is loose/broken. More sophisticated way is to test them with multimeter.
Next step I would say will be fuel injection cleaning. And if your car has fuel filter built in fuel line then replace that. It's cheap and relatively easy job.

I stalled my car this morning, which is fine whatever everyone does it. Except oh, it's an automatic :P

As a technician of the electronic repair persuasion with foot-steps in alot of different areas over the last 30-yrs, this guy knows what he's talking about - the quick tutorial on using a small propane-supply versus starting fluid is SPOT-ON. I'm watching and learning here too :) Thanks R&W Guy :-D

[MrAcer]

Dude everyone of your videos are great!! Helped me in school for mechanics and 5 years later still on my project car! Thanks!

Very appreciative of the explanation on vacuum leaks. Had a rough idle on my 2009 Honda CRV. Started looking for leaks, didn't notice any hose problem until I removed the manifold top cover. Then found the leaky hose right on top of the manifold.

And 6 yrs after this video still the best video on YouTube explaining vaccum leaks .. Great/gold information brother tyvm 👌👌

[vasylmagura]

You truly have a talent for teaching. Out of all youtube repair videos I have watched, you are actually a professional that knows his stuff.

[caspernotsofriendly]

You know your videos are so much better than others because you cut to the point and explain very carefully and in a sense that others can understand and listen too. 1 out of 10 I would say your vids are 8.5 to 9.0 that's really high up. Good job. My 350z has a lot of new mods and I have lots of vacuum issues from bad torque sequencing and over seen loose hoses. So I will try you method.

Dude!! U rock!! This helped me sooo much. One thing you should mention in the video though is that a vaccum leak can effect youre brake booster if its large enough. My brake pedal wont come all the way back up when im going beyond 40mph. I have to stick my foot under the pedal and tap it back up. I couldn't figure out where the leak was so im really glad I seen this video. Thank you

[kennethatkins]

Very simple to learn from. A sincere teacher. Love his “no nonsense” approach…

[dcphotobooths]

This is one of the best how-to repair videos I've come across in a long time. Great editing and video work.

I have watched all of his videos i believe. He is in my opinion the best source for automobile info. Very easy to follow and understanding of the entire subject. YOU are the BEST.

[bamaasbury]

I like the way you go over and explain problems. You cover them great, keep it up.

[mathewrandolph]

Best how to find a vacuum leak video. You saved me a lot of time. Sounds like my truck has a large one. Rough idle at stops, sluggish at speeds under 10mph.
