In this video I go over all the different symptoms and things you can use to find vacuum leaks on your car, a vacuum leak can cause a rough, low or high idling car and its important to find an fix because it can damage engine components but also cause poor gas mileage. There are also a few things that get overlooked when checking for vacuum leaks like the EGR Valve, PCV Valve and the Power Brake Booster which I cover in this video.

Haven't found the vacuum leak yet but thanks to you i am now blessed with honest knowledge ! Much appreciated

@caspernotsofriendly1803 4 года назад

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.

@MrAcer4 Год назад

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

@ArtemLokhovitskiy 2 года назад

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.

HELP - Your videos are AWESOME ! I have a 1994 Chevy 1500 giving me a lean code 44 yet it fails inspection because it is too rich(High HC and CO)...I have replaced the catalytic converter, the EGR valve, the o2 sensor, the spark plugs, intake manifold gasket( vacuum leak), changed the oil. and fuel filter...After 7 minutes, the check engine light comes on throwing the code 44. Dry compression was 175 to 180 on all 8 cylinders. PCV valve is good, MAP sensor is good, Throttle Position sensor is good, new o2 sensor is good all of them with correct voltages when bench tested. I even used Sea Foam and another guaranteed to pass bull crap and nothing... I can't find anymore vacuum leaks either via smoke test. SOMEBODY HELP ME PLEASE !!!

@ricoescobar4986 7 лет назад

I replaced the timing chain and the check engine light still came on after 7 1/2 minutes. A week later I pulled the break booster check valve from the break booster leaving it intact in the vacuum line and capped it. The check engine light came on at 12 minutes. I killed the engine and stepped on the brake several times really hard to test the break booster and it worked properly. I uncapped check valve and reinserted the check valve into break booster gromit then I started the engine and the brake peddle went down like it was supposed to because of the vacuum assist. The check engine light still came on. I gave up again angry. I let it set a couple of days then had to drive it 100 miles and noticed the light didnt come on. I immediately got it inspected and it passed with flying colors ! I don't know if it was the replacement of the timing chain and the computer just needed time and mileage to reset or me jacking with the break booster that fixed it, but it's DONE ! Hallelujah ! It took two years and my gas mileage went from 12.5 to 16 mpg !
