Is the gas mileage in your car or truck dropping? Learn how to find vacuum leaks easily! In this video, Sue shows you some tips for diagnosing and locating intake vacuum leaks, and shows you one safe and fun way to pinpoint where the extra air is getting in! If there is a leak in your intake, the engine is sucking in extra air that hasn't been measured by the mass airflow sensor, which throws off air/fuel mixture! The engine computer will compensate by injecting even more fuel into the engine, which will consume fuel faster!

GET OUT!!!!!!!!!!!!!!!!!!!!!!! The vacuum/soapy water thing was BEYOND what I could ever think. Do it to the exhaust all the time to check for leaks but NEVER thought of doing it on the actual throttle body flow. WOW!!!!!!!!!!!!!! That was a MOM moment. This Lady explains things like atrue Mom. LOVE THIS LADY! Have seen soooooooooooo many over the yrs She'd done and am totally floored EVERY time. OH MAN I can't wait to try this!!!!

Would it be safer to leave the air filter in place for this test, to ensure I'm not blowing debris from my vacuum cleaner into the intake of my vehicle? Thank you so much for sharing this excellent testing idea.

@Papawatata Жыл бұрын

I thoroughly enjoyed the shop vac Technique very much because it is such an awesome way of finding vacuum leaks on my own and at my pace. I went out and bought me a very inexpensive vacuum hose to do this vacuum test, this way I know for certain the vacuum hose would be super clean on the inside and not blow any dust or debris into the intake manifold. I didn't see any vacuum leaks on vacuum hoses, etc. at bank 1 or bank 2 ! However, to my surprise I did find bubbles forming at coils on the heads . I found piston number 2, 3, 5, & 7 & I stopped checking at that point. So, the Million dollar Question . . . Is it normal to see bubbles forming here??? Could this be a sign of worn out pistons or rings, or something else, perhaps very serious??? Please advise!

@webguy943 2 жыл бұрын

can you also use a smoke machine and blow it in to find the leak?

@nedmilburn 10 ай бұрын

So a vacuum leak makes the cylinder(s) run with extra oxygen, then the o2 sensor picks this up and says "we need more gas" resulting in the cylinder(s) running with more gas than needed...? Then when the air fuel mixture is balanced it reports "it's fine... don't inject extra gas" so then the engine doesn't get extra gas trim, resulting in the cylinder(s) getting too much air because of the vacuum leak... etc etc etc... ??

I only hear that sound when I turn my vehicle off would that be a vacuum leak or things just winding down?

@someone1089 Жыл бұрын

I believe you have to keep the throttle body open by putting a brick or a heavy object on the gas pedal for this test. There is a chance that you could create a new leak by pushing a brittle piece of gasket/o-ring or hose which you have to replace eventually any way. It's a good idea overall.

Am having 2010 honda civic 1.8 l 4 cyl automatic not giving proper mileage. Fuel Tank Capacity 50Liter It will give 560 kilometers if I fill up fully for the long travel. When am drive inside the city for full tank its giving me 290 to 300KM These are the steps that I have done. 1. Clean the mass airflow sensor. 2. Clean the throttle body. 3. Clean the plugs. 4. Changed the engine oil and gear oil. 5. Clean the fuel filter. 6. Clean the fuel Injector. Please assist me with this.

That mean you have less air coming in. check if your air filter is clean or not.
