Short video describing how you might find a leak in an intake manifold using a smoke machine and your scan tool. This is a 2007 Toyota Corolla S with a 1.8L. Very similar to the Vibe and Matrix. The check engine light was on with a P0171 Lean Bank 1 Code. Really common and a really easy fix. Leave your questions in the comments and subscribe to our channel.
I have 2016 toyota corolla with the same code and same engine. Going to change the intake gasket. Thanks for the video.
YOUR TAPE IS A BLESSING TO ME. THANKS
I appreciate seeing the second method as I've heard of that but it was nice to see. Regarding the first soapy water method, was the engine on??? Will you see a leak without engine on? Where did air come out of, ambient? But the second part was good.
Gracias por tu hayuda , You can do I can do 👍👍👍👍👍
Excellent video
I have 1nrfe dvvti
Low rpm lack of power need to press gas more and sound from exhaust gogogo
No rough idle
No codes
No engine light
No white smoke
39mpg atm
Change spark plugs air filter cleaned throttle body inside out
Any recommendations
Its an electronic throttle body can drive 70mph at 3500rpm but lots of noise
Did this problem trigger the check engine light? God damn cheap plastic crap….Cheap but quite expensive I'm sure
Just get a little pen laser. They show the smoke right away.
my 2000 Corolla had this problem and a replacement of the gasket resolved it immediately. Not plugs, coils, injectors, or cleaning the PCV and MAF valves along with throttle body and IAC
Love these older videos, so awkward compared to the new videos!! Thanks for all the work you do to help us out.
A 2000 Corolla is known to have gasket leaking when it is old as a common problem. Inability to climb mild inclines and rough running is odd for a Toyota 1.8L engine. I replaced fuel injectors (rebuilt, warranted set for $130) and coils and got platinum NGK plugs and at last… had the intake manifold GASKET replaced for fairly cheap. Problem disappeared on GASKET replacement after the 3 other things were done. At 275K miles on the odometer !
The guy using the impact gun while you are filming is super lame
So I might be having the same problem but on a Scion tC 06.I’ve replaced the intake itself and yet I’m still having the same problem, Any ideas?
Is it possible a leaky intake manifold gasket would cause an oil smell in the vehicle while driving with the heater on? 2003 Vibe Base
Mine ended up being the oxygen sensor. Great info tho!
how to fix? does the 1.5 do this? I got a 2007 yaris
thanks
Thanks for the great video
can a leaky gasket cause a hard start
Its noisy as i dont know what.
Great video , so in this example it was the valve cover gasket that was leaking ? Could you further explain why those two pids mean in terms of where the leak would be coming from if you have those values ?
Hi, great video thanks. I have the problem, which I understand is quite common on these, where the revs at idle, surge up & down around 2k revs when the engine is first stated, particularly from cold. I understand that a leaking intake gasket can be the cause of this problem, but my fuel trims look normal (around 0). I was wondering if you know of any other causes of this surging idle problem? Many thanks.
You're fucking awesome bro I just love how you brakes it down thanks for the knowledge bro keep it up 🤗
I know this is old but what if short term is 0.8 and long term is 32.2 🤔🤔 ?? It's a 2013 avenger 2.4
Cool
would you get a code without the check engine light on?
👍
Could see the smoke. Thanks for the video.
They said it’s not my intake manifold and my engine light is still on ? I keep being told I have an emissions leak, but where would that be at, I can’t pay $500 dollars to someone to fix my 13 year old car it’s a 2005 Toyota Corolla CE and I am being told when I go for my smog it won’t pass unless I get the engine light to go off for good? Please help me to learn how to fix my car
SWEEEET VID 🚹, THANK YOU
sweet I don't have a smoke machine but I do have a $20 bluetooth dongle and torque this should be easy
Very good
👍👍👍
hello dear I have 2003 Toyota corolla I need help you my car is start but won't stay raning I don't no what's a problem everything is good feulpump spark plugs intake air flow throttlebody camshaft senser crankshaft senser everything is put new but same problem I don't no what's problem plz help me dear
I am impressed, you did a great job and you sure simplified the processes of finding a leak. Thanks
Сделал все как на видео только когда собрал забыл вставить фишку и выскочил check engine, но потом все стало нормально когда вставил обратно.
Help plz. 2005 Corolla with p0171. So far have changed the maf with Toyota oem part. Replaced both o2 sensors with denso. Changed intake gasket. Changed catalytic converter due to a leak. Fuel pressure reads at 49 psi. Removed and cleaned fuel injectors. No vacuum leak. Car running very rough at idle. At idle, short term fuel at 0 and long at 25. At 2000 rpm, short at -4 and long jumps to 40. Any ideas plz.
Very helpful. Thanks for the shared knowledge.
Cool Deal! Won't buy a smoke machine for just a few vehicles, but I can get brake kleen or carb clean CHEAP!
Great how to video. Question: I have a 2006 Corolla Matrix with 73k miles, runs perfect-no error codes. Should I clean throttle body and MAF sensor just to be proactive or should I leave them alone? Thanks.
i have a 2009 vibe gt. is this the vacuum house that will make your breaks very hard to apply?
You are Awesome…your videos are very helpful!
Very helpful videos ,enjoy watching it
Thank you south main auto repair
Just diagnosed a 2000 celica with the same issue!!! Almost was going to call the O2 sensor because it would lag but did the brake fluid test and it tested positive for a intake leak. Good info!!!!
Too bad you didn't show us where you were spraying.
great, and the smoke was visible, the fuel trim test was great too, well done…
I'm having a problems with my 2008 Matrix, I really need to floor it to get up to highway speeds or maintain speed up hills. The car does vibrate at idle, not excessively but noticeable, and sometimes when I put into gear it it feels like the engine wants to cut off. The car only has 84,000 miles and there is no engine light on. I was wondering if the problem you mentioned might be causing this.
Thanks Eric really neat trick. Got a maybe not so easy question for ya. What maker of vehicle scanners do you recommend for the DIY'r who wants live data feedback, on screen code assist and generally a real good quality scanner?Background – I had an Actron CP9580A code reader but I gave it to my son who now lives in Texas. The only thing I don't like about this scanner is that it can't interface with Windows 8 or Win 10 computers. They have said that they plan to release a new driver for the computer/tool for the last year. I'm getting a little antsy waiting for them. I know there is a half dozen or so good scanners out there ranging from wireless to connected and from cheap and erase codes to the lets see what else is going on type of scanners. The latter is my choice for scanner capability level.
good vid…
Very good information Thanks, I will try the soapy water, I will share too
Could you also use the scan data readout of manifold absolute pressure to confirm vacuum leak? I have 1999 Toyota Corolla. Idle LTFT is rather eratic (up to 15%) but stablizes to 7% and under after long drive. It seems like maybe there's a vacuum leak at intake manifold gasket that gets sealed when gasket expands under heat? But the manifold absolute pressure stays at 10.5 inch HG to 11.3 inch HG @ idle (AC off) regardless if the LTFT is at 15% or under 7%. So, is it possible to have a vacuum leak that does not get picked up by the MAP reading? Thanks.
